Build command cannot be used as non-root (linux)

[konradkonrad]

On linux, directories that are created inside a docker mount will not map back the owner to the host-user. I.e. when running

codekoala/sencha app build

which is done as user root, the resulting build-files/directories will be owned by root. Usually the fix would be to run the container with

--user $(id -u):$(id -g)

but unfortunately this is not supported by the codekoala/sencha container:

docker run --rm -v $(pwd):/code --workdir /code --user 1001:1001 codekoala/sencha:6 app build
Sencha Cmd v6.0.2.14
[INF] Processing Build Descriptor : default
[ERR] Cannot find file: /opt/Sencha/Cmd/repo/.sencha/codegen.json
make: *** [sencha] Error 65

From my understanding on Darwin/OSX and Win, due to the way docker is started inside virtualbox, an active UID-mapping for mounts,

root <-> current user

takes place, so this is not an issue for other OS than Linux.

Thanks for reporting this. I've reproduced the behavior, and I'll try to figure out a way to fix it.

The latest codekoala/sencha:6 image appears to solve the problem for me. Does it also work for you, @konradkonrad ?

I know that it's been 2 years since last activity here and i'm sorry ;)

Currently this doesn't work for me. Here are the steps i'm executing:

docker pull codekoala/sencha:6
docker run --rm --user $(id -u):$(id -g) -v $(pwd):/code --workdir /code codekoala/sencha:6 app build

Results (checked on MacOS and Debian):

Sencha Cmd v6.2.2.36

From what i see, when running as root /home/sencha/Sencha/repo is created by sencha app build command, but it can't be created by non-root user because of lack of permissions.

Btw. running this container as sencha user works too:

docker run --rm --user sencha -v $(pwd):/code --workdir /code codekoala/sencha:6 app build

EDIT: actually it works, but only to some point. sencha user has access to /home/sencha directory, but can't modify files mounted from host with different uid/gid and crashes with:
