How to chown or write to my pipeline container for testing?

alanhardin

I have a docker image I am running to test our web application. The problem comes from a write permission 

docker-compose run --rm -v="$BITBUCKET_CLONE_DIR:/var/www/app" -u root -p 0.0.0.0:8000:80 -p 0.0.0.0:8080:8080 -p 0.0.0.0:8081:8081 app ci/run-behat-tests.sh

I do not get an error with attaching the volume. In the script I trying and run a test and I get a write permission error 

<b>Fatal error</b>: Uncaught RuntimeException: Unable to create the storage directory (/var/www/app/var/cache/test/profiler).

 

In the script I execute the following and get the following results:

echo $(whoami)

root

echo $(pwd)

/var/www/app

echo $(ls -l /var/www/app)

-rw-rw-rw-. 1 nobody nogroup 101 Apr 11 16:58 file
-rw-rw-rw-. 1 nobody nogroup 2627 Apr 11 16:58 file 
-rw-rw-rw-. 1 nobody nogroup 36300 Apr 11 16:58 file 
-rw-rw-rw-. 1 nobody nogroup 4163 Apr 11 16:58 file 
-rw-rw-rw-. 1 nobody nogroup 149 Apr 11 16:58 file 
-rw-rw-rw-. 1 nobody nogroup 105 Apr 11 16:58 file 
-rw-rw-rw-. 1 nobody nogroup 8578 Apr 11 16:58 file 
drwxrwxrwx. 5 nobody nogroup 4096 Apr 11 16:58 app

echo $(ls -l /var/www/app/var)

-rw-rw-rw-. 1 nobody nogroup 33831 Apr 11 17:01 file 
-rw-r--r--. 1 root root 42834 Apr 11 17:01 file
drwxr-xr-x. 3 root root 4096 Apr 11 17:01 cache
drwxrwxrwx. 2 nobody nogroup 4096 Apr 11 16:58 logs
drwxrwxrwx. 2 nobody nogroup 4096 Apr 11 16:58 sessions

 

How can my application write to my var/cache folder?

Hello Alan,

Due to us having Docker user namespaces enabled, you will need to have fairly loose permissions when writing to Docker containers.

In this case, the "/var/www/app/var/caches" directory is only writable by the "owner" of the directory. If you set the permissions to allow "other" (i.e. anyone) to be able to write to that directory, then you should be able to run your build as expected.

Thanks,

Phil
