|
||||
|
||||
By default, Dockron will periodically poll Docker for new containers or schedule changes every minute. You can specify an interval by using the `-watch` flag.
|
||||
|
||||
### Running with Docker
|
||||
|
||||
Dockron is also available as a Docker image. The multi-arch repo can be found at [IamTheFij/dockron](https://hub.docker.com/r/iamthefij/dockron)
|
||||
|
||||
From either an `amd64`, `arm`, or `arm64` machine, you can run Dockron using:
|
||||
|
||||
docker run -v /var/run/docker.sock:/var/run/docker.sock:ro iamthefij/dockron -watch
|
||||
|
||||
### Getting a Docker API Version error?
|
||||
|
||||
You might see something like the following error when Dockron connects to the Docker API
|
||||
|
||||
```
|
||||
Error response from daemon: client version 1.47 is too new. Maximum supported API version is 1.45
|
||||
```
|
||||
|
||||
This is because the API client library is newer than the version of the Docker API on your host. You can tell the Dockron API Client to use a compatible version by specifying `DOCKER_API_VERSION=1.45`, where the version you specify matches the API version shown when you run `docker version`. If you are running Dockron in Docker, make sure you add this to your compose environment or otherwise pass it to the container.
|
||||
|
||||
### Scheduling a container
|
||||
|
||||
First, be sure your container is something that is not long running and will actually exit when complete. This is for batch runs and not keeping a service running. Docker should be able to do that on it's own with a restart policy.
|
||||
|
||||
Create your container and add a label in the form `'dockron.schedule=* * * * *'`, where the value is a valid cron expression (See the section [Cron Expression Formatting](#cron-expression-formatting)).
|
||||
Create your container and add a label in the form `dockron.schedule="* * * * *"`, where the value is a valid cron expression (See the section [Cron Expression Formatting](#cron-expression-formatting)).
|
||||
|
||||
Dockron will now start that container peridically on the schedule.
|
||||
|
||||
If you have a long running container that you'd like to schedule an exec command inside of, you can do so with labels as well. Add your job in the form `dockron.<job>.schedule=* * * * *` and `dockeron.<job>.command=echo hello`. Both labels are required to create an exec job.
|
||||
|
||||
Eg.
|
||||
|
||||
labels:
|
||||
- "dockron.dates.schedule=* * * * *"
|
||||
- "dockron.dates.command=date"
|
||||
|
||||
_Note: Exec jobs will log their output to Dockron. There is also currently no way to health check these._
|
||||
|
||||
### Cron Expression Formatting
|
||||
|
||||
For more information on the cron expression parsing, see the docs for [robfig/cron](https://godoc.org/github.com/robfig/cron).
|
||||
@ -69,13 +41,3 @@ I intend to keep it simple as well. It will likely never:
|
||||
* Handle job dependencies
|
||||
|
||||
Either use a separate tool in conjunction with Dockron, or use a more robust scheduler like Tron, or Chronos.
|
||||
|
||||
## Building
|
||||
|
||||
If you have go on your machine, you can simply use `make build` or `make run` to build and test Dockron. If you don't have go but you do have Docker, you can still build docker images using the provide multi-stage Dockerfile! You can kick that off with `make docker-staged-build`
|
||||
|
||||
There is also an example `docker-compose.yml` that will use the multi-stage build to ensure an easy sample. This can be run with `make docker-example`.
|
||||
|
||||
## Tests
|
||||
|
||||
There are now some basic tests as well as linting and integration tests. You can run all of these by executing `make all`.
