These replace the custom audit_broadcast_cmd code. An additional env
variable MRSK_RUNTIME is passed to them.
The audit broadcast after booting an accessory has been removed.
Adds hooks to MRSK. Currently just two hooks, pre-build and post-push.
We could break the build and push into two separate commands if we
found the need for post-build and/or pre-push hooks.
Hooks are stored in `.mrsk/hooks`. Running `mrsk init` will now create
that folder and add sample hook scripts.
Hooks returning non-zero exit codes will abort the current command.
Further potential work here:
- We could replace the audit broadcast command with a
post-deploy/post-rollback hook or similar
- Maybe provide pre-command/post-command hooks that run after every
mrsk invocation
- Also look for hooks in `~/.mrsk/hooks`
Add tests for main, app, accessory, traefik and lock commands.
Other commands are generally covered by the main tests.
Also adds some changes to speed up the integration specs:
- Use a persistent volume for the registry so we can push images to to
reuse between runs (also gets around docker hub rate limits)
- Use persistent volume for mrsk gem install, to avoid re-installing
between tests
- Shorter stop wait time
- Shorter connection timeouts on the load balancer
Takes just over 2 minutes to run all tests locally on an M1 Mac
after docker caches are primed.
The code in Mrsk::Cli::Main#rollback was very similar to
Mrsk::Cli::App#boot.
Modify Mrsk::Cli::App#boot so it can handle rollbacks by:
1. Only renaming running containers
2. Trying first to start then run the new container
If there are uncommitted changes in the app repository when building,
then append `_uncommitted_<random>` to it to distinguish the image
from one built from a clean checkout.
Also change the version used when renaming a container on redeploy to
distinguish and explain the version suffixes.
In the image prune command --all overrides --dangling=true. This removes
the image git sha image tag for the latest image which prevented
us from rolling back to it.
I've updated the integration test to now test deploy, redeploy and
rollback.
Audit details
* Audit logs and broadcasts accept `details` whose values are included as log tags and MRSK_* env vars passed to the broadcast command
* Commands may return execution options to the CLI in their args list
* Introduce `mrsk broadcast` helper for sending audit broadcasts
* Report UTC time, not local time, in audit logs. Standardize on ISO 8601 format
* main:
Don't run actions twice on PRs
Further distinguish dependency verification
Naming
Reveal configured dockerfile path
Style
Distinguish from server dependencies
Distinguish from local dependency verification
Improve clarity and intent
Style
Style
Style
Add local dependencies check
Bootstrap: use multi-platform installer
* main:
Simplify domain language to just "boot" and unscoped config keys
Retain a fixed number of containers when pruning
Don't assume rolling back in message
Check all hosts before rolling back
Ensure Traefik service name is consistent
Extend traefik delay by 1 second
Include traefik access logs
Check if we are still getting a 404
Also dump load balancer logs
Dump traefik logs when app not booted
Fix missing for apt-get
Report on container health after failure
Fix the integration test healthcheck
Allow percentage-based rolling deployments
Move `group_limit` & `group_wait` under `boot`
Limit rolling deployment to boot operation
Allow performing boot & start operations in groups

Time based container and image retention can have variable space
requirements depending on how often we deploy.
- Only prune stopped containers, retaining the 5 newest
- Then prune dangling images so we only keep images for the retained
containers.
Hosts could end up out of sync with each other if prune commands are run
manually or when new hosts are added.
Before rolling back confirm that the required container is available on
all hosts and roles.
If we don't specify any service properties when labelling containers,
the generated service will be named according to the container. However,
we change the container name on every deployment (as it is versioned),
which means that the auto-generated service name will be different in
each container.
That is a problem for two reasons:
- Multiple containers share a common router while a deployment is
happening. At this point, the router configuration will be different
between the containers; Traefik flags this as an error, and stops
routing to the containers until it's resolved.
- We allow custom labels to be set in an app's config. In order to
define custom configuration on the service, we'll need to know what
it will be called.
Changed to force the service name by setting one of its properties.
Add checks for:
* Docker installed locally
* Docker buildx plugin installed locally
* Dockerfile exists
If checks fail, it will halt deployment and provide more specific error messages.
Also adds a cli subcommand:
`mrsk build dependencies`
Fixes: #109 and #237
