Docker locks up in my_init #36

Closed loleg closed 8 years ago

loleg commented 9 years ago

When running the current Docker build, the VM endlessly cycles in /sbin/my_init, with log messages like:

./run: line 33: setuid: command not found
./run: line 34: setgid: command not found
./run: line 39: respawn: command not found

It seemed something is amiss with the base image? I tried swapping out realms-base for:

FROM phusion/baseimage:0.9.15
RUN useradd -M deploy

But that had no effect.

Fixed here: 6c7095ec5a32df19e85eacf3c82258e241bc2e47 Deploying new docker image to the hub. Apparently 'env' isn't used in runsv.

Let me know if it works for you.

Thanks very much for the quick fix @scragg0x - rebuilt from your source and it is working now. I do still see some of those errors in my docker log:

ok, I will fix that in the next deploy. I guess assumed runsv was just like upstart... when it's just a bash script after all.

Just a quick note. After spending some time trying to figure out this problem I have found this bug. It seems that the realms-wiki@DockerHub the latest version availabe is 0.5.1 so I think this has not been fixed yet.

EDIT: but if you build from the Dockerfile with a command like this:

(sudo) docker build -t yourname/realms-wiki .

(Add sudo only if you need it to run the docker command).

I suggest to use your name for naming the image not to conflict with the official realms/realms-wiki on Docker Hub.

With this everything works.

Thank you @CristianCantoro, that did the trick. Just a note you'll need not only the Dockerfile, but also the shell script. You can get these with:

wget https://raw.githubusercontent.com/scragg0x/realms-wiki/master/docker/Dockerfile
wget https://raw.githubusercontent.com/scragg0x/realms-wiki/master/docker/realms-wiki.sh
CristianCantoro commented 9 years ago

@theherk, yes. I was assuming that the instructions were for people that have cloned the repo and could edit directly the Dockerfile (and have all the rest on their system).

eric-schleicher commented 9 years ago

Sorry, I'm a little slow on the uptake... what exactly needs to be changed in the Dockerfile and/or realms-wiki.sh file to get passed the problem that @loleg brought to attention?

i 'wgetted' the files that @theherk put references to as well as cloned the repo locally both with the same result.

Superficially this looks like the user running the script in the container lacks suffecient priveledges (to fee the commands? (limit, respawn, etc)

Please advise, this looks like a great wiki, excited to give it q real whirl.

issue should be fixed in b30c140e86e52da1aee4b1e6432428d933161480. I am attempting to deploy now.

@eric-schleicher, The question is from which source was the image that you are running was built. You are running user/realms-wiki, but was that built from the repository online or from the files that your pulled down?
