openhub is a small glue service between an Open Build Service instance and the Docker Hub.
The main task of openhub is to check whether there is an update on an RPM, and then trigger a Docker image rebuild on a tag. This is done through a configuration that looks like this:
services:
portus-head:
project: "Virtualization:containers:Portus"
distribution: "openSUSE_Leap_42.3"
architecture: "x86_64"
package: "portus"
repository: "opensuse/portus"
tags: ["head"]
portus-2.3:
project: "Virtualization:containers:Portus:2.3"
distribution: "openSUSE_Leap_42.3"
architecture: "x86_64"
package: "portus"
repository: "opensuse/portus"
tags: ["2.3", "latest"]In the above example, we are telling openhub to listen for changes on
Virtualization:containers:Portus and Virtualization:containers:Portus:2.3
(particularly on the portus package from Leap 42.3 and the x86_64
architecture). Whenever there is a new revision, then it will trigger a Docker image rebuild
on the proper repository/tag combination.
You can run openhub like this:
$ openhub <path-to-config-file>
We also provide a Docker image and a docker-compose.yml file as an example on
how to deploy it. Note that you also need to specify some environment variables:
- OPENHUB_OBS_USER: the user to be used on the Open Build Service server.
- OPENHUB_OBS_PASSWORD: the password for the above user.
- OPENHUB_DOCKER_TOKEN: the token to be used when authenticating with the DockerHub. A token can be generated by activating triggers on the "Build Settings" tab on the repository page.
You can install openhub from source by cloning this repository and then
performing the following command:
$ make installYou could build this project as any other Go binary with go build, but this is
not recommended. Instead, use the default make target:
$ make
# or the equivalent `make openhub`
With this command, openhub will be built with the desired build flags and
setting the proper version for it. Note that the build can be further customized
with the BUILD_FLAGS variable. So, you could pass extra arguments like so:
$ make BUILD_FLAGS="-v"
When doing this you should be careful to not conflict with a default build flag.
Unit testing is performed through the test-unit make target:
$ make test-unit
Besides running tests, we also perform some validation tests on the code. These tests can be run like this:
$ make validate
The CI will only run the ci target, which will in turn:
- Run all validators.
- Run unit tests.
It is recommended that you perform make ci before submitting a pull request,
and check that it ran successfully.
