jmtd → log → Concreate and Red Hat JBoss OpenShift image sources
Last year I wrote about some tools for working with Docker images. Since then, we've deprecated the dogen tool for our own images and have built a successor called Concreate.
Concreate takes a container image definition described in a YAML document and
generates an output image. To do so, it generates an intermediate
along with the scripts and artefacts you references in the YAML file,
and by default invokes
docker build on the result.
However, it can use other builders, such as the OpenShift Build
Service, which is what we use for our production
Concreate can also manage running tests against the image. As with the Container Testing Framework that I mentioned last time, these tests are defined using the Behave system.
In related news is that we have published the sources for all of our images. You can now go and read the image.yaml file for EAP 7 on OpenShift to give you an example of what a real image using Concreate looks like.
