Load the hosts from the contexts before trying to build.
If there is no context, we'll create one. If there is one but the hosts
don't match we'll re-create.
Where we just have a local context, there won't be any hosts but we
still inspect the builder to check that it exists.
Occasionally in CI things run slowly and it takes more that 1 second
for a cli test to run, so let's allow any value for the runtime in the
hook checks.
To avoid polluting the default SSH directory with lots of Kamal config,
we'll default to putting them in a `kamal` sub directory.
But also make the directory configurable with the `run_directory` key,
so for example you can set it as `/var/run/kamal/`
The directory is created during bootstrap or before any command that
will need to access a file.
Useful for checking the status of CI before deploying. Doing this at
this point in the deployment maximises the parallelisation of building
and running CI.
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.
Rather than waiting 5 seconds and hoping for the best after we boot
docker compose, add docker healthchecks and wait for all the containers
to be healthy.
1. Don't raise lock error for non-lock issues during lock acquire
(see https://github.com/mrsked/mrsk/pull/181)
2. If there is an error while the lock is held, don't release the lock
and send a warning to stderr
Add a deploy lock for commands that are unsafe to run concurrently.
The lock is taken by creating a `mrsk_lock` directory on the primary
host. Details of who took the lock are added to a details file in that
directory.
Additional CLI commands have been added to manual release and acquire
the lock and to check its status.
```
Commands:
mrsk lock acquire -m, --message=MESSAGE # Acquire the deploy lock
mrsk lock help [COMMAND] # Describe subcommands or one specific subcommand
mrsk lock release # Release the deploy lock
mrsk lock status # Report lock status
Options:
-v, [--verbose], [--no-verbose] # Detailed logging
-q, [--quiet], [--no-quiet] # Minimal logging
[--version=VERSION] # Run commands against a specific app version
-p, [--primary], [--no-primary] # Run commands only on primary host instead of all
-h, [--hosts=HOSTS] # Run commands on these hosts instead of all (separate by comma)
-r, [--roles=ROLES] # Run commands on these roles instead of all (separate by comma)
-c, [--config-file=CONFIG_FILE] # Path to config file
# Default: config/deploy.yml
-d, [--destination=DESTINATION] # Specify destination to be used for config file (staging -> deploy.staging.yml)
-B, [--skip-broadcast], [--no-skip-broadcast] # Skip audit broadcasts
```
If we add support for running multiple deployments on a single server
we'll need to extend the locking to lock per deployment.
