This new feature will anonymize emails in the Postfix logs. This allows
you to keep them indefinetely while being compliant with GDPR.
Based on excellent work on [this pull request](https://github.com/bokysan/docker-postfix/pull/91).
Check `README.md` for more details.
* copy other specs over
I want to copy over loadBalancerIP to grab a predefined static ip
* removed hardcoded LoadbalancerIP
* Set theme jekyll-theme-slate
* update README
* test service specs are copied over
* undo config changes
* remove config file
While these tests are neccessary, they cannot be completed
immutably. They rely in access and refresh token from Google
and these expire -- we would need to devise a smart way of
getting them every time before the tests are run.
- It's now possible to choose the logging type - either 'plain' or
'json'
- The code is ready to support multiple integration tests (with
different configurations)
- `OPENDKIM_` and `POSTFIX_` variables are handled properly and recorded
in the corresponding files. (This had a downfall that `bash` now needs
to be installed, so we can probably simplify some of the shell
scripts.)
Summary
^^^^^^^
This commit refactors the code base to be more manageble and
prepares the groundwork for tests.
Refactoring
^^^^^^^^^^^
Files are now moved to subdirectories, all for the sole purpose of
easier management. Tests live in their own folders, as well as configs
and other files.
Test framework
^^^^^^^^^^^^^^
Two new important scripts/directories are available:
- `unit-tests.sh` / `/unit-test` which executes unit tests across shell
scripts, and
- `integration-test.sh` / `integration-tests`, which spins up the
container and tries to send the email.
Both tests use the [BATS](https://github.com/sstephenson/bats) framework
for testing. To create a new test, simply drop a `.bats` file into a
corresponding directory.
Functions have been extracted into `common-run.sh`, to be able to test
them independently.
DKIM_SELECTOR
^^^^^^^^^^^^^
It is now possible to specify a DKIM selector to use (instead of
the default "mail"). See `README.md` for more details.
JSON logging
^^^^^^^^^^^^
WIP: rsyslog will now output JSON logs. This is especially important
if you plan on deploying the image into Kubernetes, as [Prometheus](https://prometheus.io/)
can handle logs in JSON much easier.
TODO: Make this an optional feature, to not confuse existing users.
Expand the `README.md` a bit to better explain what's needed to get the server up and running.
It seems that a lot of users are trying to use this image and running into issues. This should help out a bit to get them started.
This PR allows setting an empty `ALLOWED_SENDER_DOMAINS` variable. The default behaviour remains the same (empty `ALLOWED_SENDER_DOMAINS` will throw an error), but it is posible to override this behaviour via a new variable `ALLOW_EMPTY_SENDER_DOMAINS`.
This fix makes it more explicit that "mail" segment must be used
with this DKIM and adds a few more code to the DKIM part to make
it more resillient and useful.
