Thanks! ("help docker:provision" doesn't work in 4.2.8 because of the
InvocationTargetException issue (known issue, I know))
Side note: dockerd on GNU/Linux by default doesn't listen to any IP ports,
but only to a domain socket, see e.g. https://stackoverflow.com/a/52170405
Configuring dockerd to listen to a port is only a google search away,
but it may simplify things if the karaf docker support tries connecting
to the domain socket by default...?
Should I make a JIRA for using domain socket by default on GNU/linux?
On the docker:provision: it seemed that the first docker:provision <name>
did the right thing, but the second "docker:provision" just pulled the
the image the first provision had made:
karaf@root()> docker:provision ukelonn-demo
{"status":"Pulling from library/java","id":"8-jre-alpine"}
{"status":"Digest:
sha256:6a8cbe4335d1a5711a52912b684e30d6dbfab681a6733440ff7241b05a5deefd"}
{"status":"Status: Image is up to date for java:8-jre-alpine"}
karaf@root()>
It also looks like docker:provision always uses the same docker image:
java:8-jre-alpine?
Is there a way to flush what docker:provision has made?
And is there a way to extract the image docker:provision has made and
make it into something that can be pushed to dockerhub?
Or do I need to look at more traditional docker image building, using a
Dockerfile?
Thanks!
