"docker-compose up --no-build" seems to be executing Dockerfile build steps #5644

Closed mnieber closed 6 years ago

mnieber commented 6 years ago

docker-compose version 1.19.0dev

When I run docker-compose --verbose -p test up --no-build I'm getting this in my output:

compose.cli.verbose_proxy.proxy_callable: docker inspect_container -> {'AppArmorProfile': '',
 'Args': ['install', '--modules-folder=/srv/jobpal/node_modules'],
 'Config': {'AttachStderr': False,
            'AttachStdin': False,
            'AttachStdout': False,
            'Cmd': ['yarn',
                    'install',
                    '--modules-folder=/srv/node_modules'],
            'Domainname': '',
            'Entrypoint': None,

This seems to refer to the following step in my Dockerfile:

RUN yarn install --modules-folder /srv/node_modules

Since I'm using the --no-build option, I expected docker-compose to ignore this build step and only execute the CMD line:

# Run api service
CMD ["node", "index.js"]

Is this a bug?

shin- commented 6 years ago

You're misinterpreting this. Note how the verbose line you quote starts with docker inspect_container; this is exactly what Compose is doing here, retrieving information about containers to inform its behavior. The retrieved information happens to contain said container's command. Without context it's hard to say what caused this specific container to be inspected, but long story short, it isn't a "build step" and it's not a bug.

HTH

mnieber commented 6 years ago

@shin- Sorry, I left out one other important bit of information, which is: the compose up command stopped because yarn install could not reach the node package repository. The reason is that my firewall is blocking it, but the important thing is: it should not try to execute this line.

If you are interested, I could try to create a minimal example that reproduces this behaviour, so it can be inspected more easily.

shin- commented 6 years ago

Can you share the full verbose logs for the up command you're running?

mnieber commented 6 years ago

I simplified my example a bit, and am posting the docker-compose.yml and verbose log output below (I had to anonymize a few names in the docker-compose.yml and output, but otherwise it's the verbatim output):

Okay - I see that the yarn install ... command is happening, but this is at runtime, not build time. It seems you're not specifying a command for the foobar-api service, which means it will use the default command associated with the foobar:foobar-api image - and that default command for some reason seems to be yarn install --modules-folder=/serv/foobar/node_modules (either because your Dockerfile specifies it as a CMD entry, or because the image you're inheriting via FROM set that as its CMD and wasn't overridden).

What you want to do is override the default command with the one you actually want to run, either by updating your Dockerfile or specifying the appropriate command in your Compose file.

Sorry, I wanted to post the Dockerfile as well, but forgot to press Comment. Here it is (the CMD just starts node, it does not install packages):

FROM foobar/base:latest

ADD . /srv/foobar/src/foobar-api
WORKDIR /srv/foobar/src/foobar-api

# install api package
ENV NODE_PATH /srv/foobar/node_modules/
RUN yarn install --modules-folder /srv/foobar/node_modules

# Expose api port
EXPOSE 8003

# Run api service
CMD ["node", "index.js"]

@mnieber Looks like you need to re-build / re-tag your image to use the result of this Dockerfile, because that's not the image that's being used by Compose right now - it's most likely outdated. You can check for yourself if you run docker inspect foobar:foobar-api and look at the Config.Cmd field.

@shin- Thanks, that solved it! I was bitten by something unexpected, I will explain. The yarn install call was never a CMD instruction in my Dockerfile, but it was used in a call to docker run, followed by a call to docker commit that saves the docker container as a docker image (in this case: foobar:foobar-api). I use this as a trick to update the packages in my foobar:foobar-api image without having to reinstall all packages from scratch. I was not aware however that this alters the Cmd value that is stored inside the foobar:foobar-api image (to be honest, I still find this surprising).

I think that for my use-case, I can just set the command option to node index.js in my docker-compose.yml. Thanks very much for your help!

Glad I could help! :+1:
