Using `set -ex` will exit the script as soon as a non-zero exit code is returned, such as when the docker image fails building the docs due to `build --strict` catching broken links. This also removes the need for `|| exit` when changing directory.
This seems fine for a small script, but AFAIK an alternative fix is just adding `|| exit` to the end of the `docker run` command too? There appears to be advice [against adopting `-e` carelessly](http://mywiki.wooledge.org/BashFAQ/105), while others [encourage `-e`](http://redsymbol.net/articles/unofficial-bash-strict-mode/). I know that several maintainers here have preference towards `set -e` so I've kept the original PR solution.
Additionally:
- `-x` is used to improve command visibility when reviewing the workflow log output.
- `--name` isn't necessary, but was part of the original PR.
- I've chosen not to include `-o pipefail`, only because no pipes are used in this script.
* docs(fix): Fix broken links
* ci(docs): Added inline docs
Extra documentation context for maintainers to quickly grok what's going on.
* chore(docs): Minor typo fix by wernerfred
Added from their related PR by request.
* docs(ssl): Adjust heading levels for provisioning sections
- Group provisioning sections under one heading level.
- Use `attr_list` syntax for headings to make the ToC sidebar entry less verbose.
* docs(ssl): Minor fixes
Typos, formatting.
* docs(ssl): Rephrase Traefik wildcard support
Split the line out into multiple with better phrasing.
* docs(ssl): Add FQDN section
We briefly mention the same info twice on the docs page, but as it applies to all provisioners in general, it's been given it's own detailed section with examples.
Single section to inform users about an FQDN, how it's configured and understood by `docker-mailserver` for both Docker CLI and `docker-compose.yml` variations.
Adds note about wildcard support and bare domains to clear up any confusion configuring FQDN for these two.
Additional note about Certbot using symlinks for it's cert storage.
* chore: Add FQDN comment for `docker-compose.yml` example config
This was a community contributed guide from the Github Wiki prior to docs migration. I've rewritten it by restructuring the content, introducing numerical steps and revising some of the content, while removing third-party software that was unnecessary (the original authors and content related to their use-case, Moodle).
See the PR for further details and reference links regarding the original documents history.
The PR provides improved diff via separate commits scoping changes at the correct change bounds, unfortunately the full diff doesn't align to those boundaries well making it more difficult to review vs individual commits.
Below commit messages are roughly equivalent to what is listed on the PR. The PR provides additional linked resources for reference to support commit message statements.
---
* docs: Add CT log warning
- Added a warning to make users aware that using a public CA like _Let's Encrypt_ will publicly log information that may be somewhat sensitive, or undesirable to have historic records made public which cannot be redacted.
* docs: Revise the manual `certbot` guide
- The `letsencrypt` repo that was linked early in this guide now redirects to the [Certbot repo](https://github.com/certbot/certbot).
- More explicit volume mount instruction for CertBot; the local location was a tad vague.
- Better clarified `/etc/letsencrypt/live` contents structure, as well as FQDN info. Removed the misleading `fqdn:` from `docker-compose.yml` example snippet.
* docs: Revise certbot with Docker guide
- General rewrite of the Docker Certbot section with additional tips (_renewals with automation, and using a alternative CA_).
- Generalized tone and paths in content.
- Update volume mount paths to be consistent with recent normalization effort.
- Moved some instructions into inline-comments for script examples instead.
* docs: Revise Docker with `nginx-proxy` and `acme-companion`
- Break apart into individual steps, indenting content into the step as appropriate.
- Use normalized volume paths (`docker-data/<service>/` prefix).
- `letsencrypt-nginx-proxy-companion` has _changed project name to `acme-companion`_, and _transferred to new maintainers and the `nginx-proxy` organization_. This also affects the DockerHub image references.
- `acme-companion` has _switched from using `simp_le` to `acme.sh`_ for provisioning certificates. This requires mounting an additional volume for persisting provisioner state.
- The dummy container (_webmail_) is no longer `library/nginx`, just [`nginx`](https://hub.docker.com/_/nginx). This container also doesn't appear to be required. I've verified that the ENV can be given to the `mailserver` service container directly. Retained for now.
* docs: Revise Docker Compose with `nginx-proxy` and `acme-companion`
Heavy rewrite of this section. Like the previous commit mentions, this content was outdated. It has been simplified with improved documentation and reference links.
It also looks like there was a mistake in the existing config example as it uses the regular `nginx` image instead of `nginx-proxy`.
- The bulk of the `mailserver` service has been removed, users are advised to have an existing `docker-compose.yml` config for `docker-mailserver` and update only what is relevant to integrate with the cert provisioner.
- `DEBUG` is _false_ by default.
- The `networks:` portion of the example appears to be taken from upstream, _which that has since dropped it_. While we could continue to document this, I consider it more of an advanced config detail that we don't need to touch on in our docs.
- The `htpasswd` volume is unnecessary, only relevant if using _"Basic Authentication"_ to protect access to web service endpoints. `conf.d/` is also not required by default, it can be useful for the `standalone` mode (_documented as a `tip`_). Remaining volumes have inline-comments to document their purpose.
- `volumes_from:` is _not supported in v3 Compose format_, _only v2_ and the Docker CLI. I did not want to advise v2, so I've duplicated the volumes between the two containers instead. Internally `acme-companion` would rely on `volumes_from:` to identify the `nginx-proxy` container, it _provides alternative discovery methods_, the label is outdated and refers the legacy label (_their script logic is the same_); using the ENV `NGINX_PROXY_CONTAINER` seemed most appropriate and has been added.
- Upstream `acme-companion` docs only cover support for v2 Compose format. _There is a note regarding `nginx-proxy`_ having _volumes configured in it's Dockerfile_. Providing a volume for `/etc/nginx/dhparam` is required to avoid creating anonymous volumes each run of `nginx-proxy`. I've used a named data volume here to make it stick out more, it's not desirable and upstream should fix this, then we can drop it.
- I've also opted to only demonstrate the _Two Container (Basic) setup_ that upstream documents. Previously our docs have been showing _`docker-gen` with the Three Container (Advanced) setup_, which allows for not having the Docker API socket attached as a volume to a container exposed to the web. This reduces the security a bit, and I have not mentioned that on our docs. I could caution the reader with a link to upstream about the risk, but I don't think we should maintain the `docker-gen` setup.
* docs(fix): Update anchor links
These mismatched the current section headers they were meant to link to.
"Brief" summary/overview of changes. See the PR discussion or individual commits from the PR for more details.
---
Only applies to the `docs/content/**` content (_and `setup` command_). `target/` and `test/` can be normalized at a later date.
* Normalize to `example.com`
- Domains normalized to `example.com`: `mywebserver.com`, `myserver.tld`, `domain.com`, `domain.tld`, `mydomain.net`, `my-domain.tld`, `my-domain.com`, `example.org`, `whoami.com`.
- Alternative domains normalized to `not-example.com`: `otherdomain.com`, `otherdomain.tld`, `domain2.tld`, `mybackupmx.com`, `whoareyou.org`.
- Email addresses normalized to `admin@example.com` (in `ssl.md`): `foo@bar.com`, `yourcurrentemail@gmail.com`, `email@email.com`, `admin@domain.tld`.
- Email addresses normalized to `external-account@gmail.com`: `bill@gates321boom.com`, `external@gmail.com`, `myemail@gmail.com`, `real-email-address@external-domain.com`.
- **`faq.md`:** A FAQ entry title with `sample.domain.com` changed to `subdomain.example.com`.
- **`mail-fetchmail.md`:** Config examples with FQDNs for `imap`/`pop3` used `example.com` domain for a third-party, changed to `gmail.com` as more familiar third-party/external MTA.
* Normalize config volume path
- Normalizing local config path references to `./docker-data/dms/config/`: `./config/`, `config/`, \``config`\`, `/etc/` (_volume mount src path prefix_).
- Normalize DMS volume paths to `docker-data/dms/mail-{data,state,log}`: `./mail`, `./mail-state` `./data/mail`, `./data/state`, `./data/logs`, `./data/maildata`, `./data/mailstate`, `./data/maillogs`, (_dropped/converted data volumes: `maildata`, `mailstate`_).
- Other docker images also adopt the `docker-data/{service name}/` prefix.
* `ssl.md` - Use `dms/custom-certs` where appropriate.
* Apply normalizations to README and example `docker-compose.yml`
---
Common terms, sometimes interchangeably used or now invalid depending on context: `mail`, `mail container`, `mail server`, `mail-server`, `mailserver`,`docker-mailserver`, `Docker Mailserver`.
Rough transformations applied to most matches (_conditionally, depending on context_):
- 'Docker Mailserver' => '`docker-mailserver`'
- 'mail container' => '`docker-mailserver`' (_optionally retaining ' container'_)
- 'mail server' => 'mail-server' / '`docker-mailserver`'
- 'mail-server' => '`docker-mailserver`'
- 'mailserver' => 'mail-server' / '`docker-mailserver`'
Additionally I checked `docker run` (_plus `exec`, `logs`, etc, sub-commands_) and `docker-compose` commands. Often finding usage of `mail` instead of the expected `mailserver`
Additionally changes `mailserver` hostname in k8s to `mail` to align with other non-k8s examples.
---
* drive-by revisions
Mostly minor revisions or improvements to docs that aren't related to normalization effort.
Initial pass for achieving more consistency with docker-compose related configs.
* Set DMS_DEBUG to 0
* align with default docker-compose.yml

This feature was originally introduced by the PR: https://github.com/docker-mailserver/docker-mailserver/pull/1463
- Assign default DH params to use via Dockerfile build instead of copy and update at runtime.
- Parameterized service names and paths.
- Refactor postfix and dovecot dh methods to wrap shared dh logic
- I don't see any value in checking the alternative service for dh params file to copy over, so that's now dropped too.
- Another conditional check is dropped and the default fallback message for existing DH params file is no longer relevant.
- Improved the remaining `_notify` messages. Collapsing the warning into a single logged message also seemed relevant.
- There is no apparent need for special handling with `ONE_DIR=1`. Dropped it.
- Refactor DH params tests
- Combine custom and default DH param tests into single test file
- docs: Add instructions to use custom DH params
There is no official documented support for custom DH parameters. As no guarantee is provided, this is considered an internal change, not a breaking one.
* docs: Improve FAQ entry for `mail-state` folder
- Links to relevant script logic.
- Better list of services data moved to `mail-state`.
* Update docs/content/faq.md

Decoupling setup process from `setup.sh` script by introducing a setup script _inside_ the container that coordinates the setup process.
**This is not a breaking change**. This way, we do not have to keep track of versions of `setup.sh`.
This change brings the additional benefit for Kubernetes users to be able to make use of `setup` now, without the need for `setup.sh`.
---
* move setup process into container; setup.sh versioning not needed anymore

Centralize the collection of the HOSTNAME and DOMAINAME so that it's predictable and uniform across the various scripts (using the helper). Ensure it supports the various configurations users can have (both subdomain and without subdomain, override and no override).
---
* using _obtain_hostname_and_domainname helper + covers when not a subdomain
doc: OVERRIDE_HOSTNAME takes priority
* added tests for non-subdomain hostname + further improvements
* moved SRS DOMAINANME tests into hostname test file + Allowing DOMAINNAME ENV to override what would be automatically set

* docs: SSL - Deprecate internal self-signed cert tool
We no longer support this method with `setup.sh` from v10 onwards, `SSL_TYPE=self-signed` remains supported however. Advice has been revised for users to provide their own self-signed cert or use an external tool with an example provided.
* chore: typo fix
* chore: fix docker cmd

* docs(ci): Support deploy previews for documentation
Each PR that contributes to docs will generate a unique (to that PR) URL to preview the PR live for review.
* docs(ci): Split workflow
To support previews from non-collaborators PR contributions, we cannot rely on secrets access from workflows triggered by the `pull_request` event.
To do so securely, according to official advice from Github, we must run the third-party contribution in the restricted `pull_request` context, and then use a 2nd workflow to deploy the build (which requires secrets access).
* docs(ci): Rename doc workflows + add commit status
Better naming convention for documentation workflows.
Split workflow only indicated status on PR of the 1st stage (building the preview to deploy), not the deployment progress/result. This needs to be managed more directly until the action better supports split-workflow scenario.
* docs(ci): Add concurrency limit to preview deploy workflow
This would be more ideal on the 2nd phase workflow (`workflow_run`), however keeping it simple for now.
Limits the concurrency of the initial pull request workflow for documentation contributions that have PRs with multiple event triggers in a small time span (before the workflow triggered would complete). The main benefit is to avoid redundant deploys if the initial workflow has been triggered again to build the PR once more. It only will work against concurrent workflows for that PR in the 1st stage, if an existing `workflow_run` (2nd stage) is active for that PR it will not be cancelled.
* docs(ci): Add sponsor branding for deploy preview service
A requirement from Netlify for the [sponsored OSS organization plan](https://www.netlify.com/legal/open-source-policy).
* docs(ci): Use a shared build script
Production and Deploy Preview builds are now maintained via the same shell command, so version updates of docker image is in one place.
Additionally deletes unnecessary build output which upstream provides no support to exclude.
* docs: Add a custom 404 page
This is used by the preview deploys on Netlify. Production deploys on Github Pages require a top-level 404 page manually deployed (since all are deployed to a version subpath).
This 404 page was custom built and optimized by me. This is the final minified output, separate source to build is available if needed.
---
Likewise the `favicon.ico` is a fallback for browsers that implicitly check the domain root for this file if the SVG isn't supported/preferred. Browsers check for this file without it being present in the HTML head meta elements.
On Github Pages the `favicon.ico` isn't likely to be picked up by even top-level as typical deployment has the project name as a subpath. The docs however reference a PNG favicon which should be widely supported.
The `favicon.ico` was generated by RealFaviconGenerator online tool with SVG source input. It contains 16px, 32px and 48px sizes. Quality is better than the `favicon.io` generator.
* chore: Optimized logo
SVG source cleaned up and optimized with SVGO 2.3.
Minified versions (`.min.svg` extension) remove unnecessary data and white-space to reduce size further for production use. This extension better differentiates by filename that it's different from the `src` version.

During the long-lived PR, multiple contributions to the existing Github Wiki were made, this commit applies those here and mentions the files and authors attributed to the changes:
JaapD: dkim.md + forward-only-mailserver-with-ldap-authentication.md
Added corrections to `setup.sh config dkim` command.
Added compatibility warning about 4096-bit key sizes or greater.
Added ldap tip.
---
fred727-temp: optional-config.md
Added a mention for `user-patches.sh`.
---
Semir Patel: setup.sh.md + debugging.md
Minor corrections. Additionally corrected `tvial` references that had already been updated in this PR series.
---
Stefan Neben: kubernetes.md
> Port 25 proxy protocol configuration in master.cf was missing
docs(sync): Add Github Wiki contributions
> IMAP with STARTTLS is also active, so we need that option here as well
docs(sync): Add Github Wiki contribution
Also removed the FAQ inline heading link for Rancher. It's not a relevant link (as the question already expects knowledge of Rancher), and breaks out of the bg colour heading style due to the HTML generation logic from mkdocs.
Various PR commits related to the nav section have been merged together:
docs: Fix indentation for linter check
docs: update edit uri to content subdirectory
docs: add ghcr link
docs: shorten nav entry name
docs: quote ghcr nav entry
docs(config): update nav section for relocated documents
Additional nav section fixes:
- consistent usage of quotes
- eclint padding error
- wrong indentation of pop3
- remove a leading slash from a filepath
Consistency pass, formatting cleanup and fixes, introduce admonitions, add front-matter.
---
docs: Add front-matter
---
docs: Fix and format links
- Some links were invalid (eg files moved or renamed)
- Some were valid but had invalid section headers (content removed or migrated)
- Some use `http://` instead of `https://` when the website supports a secure connection.
- Some already used the `[name][reference]` convention but often with a number that wasn't as useful for maintenance.
- All referenced docs needed URLs replaced. Opted for the `[name][reference]` approach to group them all clearly at the bottom of the doc, especially with the relative URLs and in some cases many duplicate entries.
- All `tomav` references from the original repo prior to switch to an organization have been corrected.
- Minor cosmetic changes to the `name` part of the URL, such as for referencing issues to be consistent.
- Some small changes to text body, usually due to duplicate URL reference that was unnecessary (open relay, youtous)
- Switched other links to use the `[name][reference]` format when there was a large group of URLs such as wikipedia or kubernetes. Github repos that reference projects related to `docker-mailserver` also got placed here so they're noticed better by maintainers. This also helped quite a bit with `mermaid` external links that are very long.
- There was a Github Wiki supported syntax in use `[[name | link]]` for `fetchmail` page that isn't compatible by default with MkDocs (needs a plugin), converted to `[name][reference]` instead since it's a relative link.
---
docs: Update commit link for LDAP override script
Logic moved to another file, keeping the permalink commit reference so it's unaffected by any changes in the file referenced in future.
---
docs: Heading corrections
Consistency pass. Helps with the Table of Contents (top-right UI) aka Document Outline.
docs: codefence cleanup
---
docs: misc cleanup
---
docs: Add Admonitions
Switches `<details>` usage for collapsible admonitions (`???`) while other text content is switched to the visually more distinct admoniton (`!!!` or `???+`) style.
This does affect editor syntax highlighting a bit and markdown linting as it's custom non-standard markdown syntax.
Adds some third-party CSS as`mkdocs-material` doesn't seem interested in a PR to upstream this feature to the community.
---
Uses a font icon approach for the external link as alternatives like SVG was reported in PR as breaking on Chrome.
The logo has been made larger than theme default, it needs a little push from the left to align well with the tabs below it.
---
Unrelated: Additionally experiment with the Instant Navigation feature.
---
docs(styles): Various improvements
Multiple related commits from original PR have been squashed into this. Some messages may be redundant due to loss of history.
---
docs(styles): Minor improvements
- Use relative path for external-link
- UI enhancement for version selector
- Improve inline documentation for `customizations.css`
Make separate styling sections more evident (since we're not using multiple files or build tools).
---
docs(styles): Replace permalink to fix UX bug
---
docs(styles): Replace permalink feature for alternative approach
Previous commit already switched `permalink` for `anchorlink` option, but the `#` symbol had UI concerns regarding font-size/scale and fitting into the gutter.
Gutter change reverted, switch to REM units and symbol replaced by thin vertical rectangle scaled by font height, far better consistency for placement.
---
docs(styles): Refactor the heading link style
Effectively ended up making a border-left line style, just not as consistent and more complicated. Fixed that by adjusting styles.
Adds optional background fill and restores inline code style for headings.
It seems it may have be simpler to just use 'mike'..
Additionally squashes related commits providing minor fixes + improvements:
- Use a job dependency (`needs`) to avoid `push` event race conditions due to parallel jobs.
- Improve workflow file documentation via inline comments.
- Make ShellCheck linting happy.
- `chown` doesn't seem to work unless on the default branch for CI. Opted to use the docker `--user` approach instead.
Adds the SVG logo I created (composited rather) in mid-feb in one of my PRs that went slightly off-topic about migrating docs from Github Wiki.
Enables the logo and favicon in `mkdocs.yml`. SVG sources for both full colour and simplified monochromatic are included along with PNG images for use anywhere else, such as the organization logo.
The two SVG of the same names from `src` dir, are used by the docs and have been processed through SVGOMG, an SVG file size optimizer. Any future modifications should use the source files.
