• start_server.sh, applyConfig.sh- will apply props in alphabetic order. closes #127
• 8.5.x - for users interested in using older versions of WAS to build the image themselves. Closes #141

thanks so much for this contribution @DSTOLF! We really appreciate the time it took to create it.

My only comment is if we can make the userID and groupID configurable arguments, with defaults of 1001:0, to match our Liberty docker image (https://github.com/WASdev/ci.docker/blob/master/ga/18.0.0.4/kernel/Dockerfile#L23). That way you can easily switch to 510:500 if you wanted.

Hi @arthurdm

Unfortunately, the userID and groupID can't be configurable arguments, as the COPY command on the Dockerfile doesn't have variable expansion.

If you want, I can change it to 1001:0, but whatever the IDs are, they'll be hardcoded. I suppose I can come up with some regex to easily change that, but I don't think you'll want to have that in your repo.

Please let me know how you want it done.

Regards, Daniel Stolf

@DSTOLF - ah, interesting - I wasn't aware of that limitation of COPY...thx for pointing that out! I have now added a +1 to the GH issue.

Until docker is fixed, if you could change it to be 1001:0, that would be great.

@arturdzm -after the uID/gID changes, this PR looks good to me. Can you please verify?

[DSTOLF]

@arthurdm

Just to be sure, it's uid=1001 and gid=0, right?

If so, all the Dockerfiles that I have changed to multi-stage build are fixed now.

9.0.0.9/Dockerfile and 8.5.x/Dockerfile (which was based on 9.0.0.9) are not multi-stage, so I didn't see any reason fiddle with uid and groupid there.

Regards!

@DSTOLF
Thank you for the update, yes uid,gid are correct now.

The rest looks good @arthurdm
