Local development issue with Docker, Composer and file permissions

[SOHELAHMED7]

Enter into bash shell of a Docker container:

docker-compose exec --user=$(id -u) php bash

Run

composer remove <package>

Below error is faced:

In JsonFile.php line 184:
                                                                                
  file_put_contents(./composer.lock): failed to open stream: Permission denied  
   

Need few changes Dockerfile related to permission of files.

Similar issue: serversideup/docker-php#179

Temporary workaround:

# enter in CLI using root user in Docker container
docker-compose exec --user="root" php bash

Can be fixed by

chown -R $USERNAME:$USERNAME $HOME \
&& chown -R $USERNAME:$USERNAME /app

in Dockerfile

Below steps fixed this issue:

• Delete composer.lock file and vendor directory (in my case these were owned by different user)
• enter in CLI of container (make cli)
• run composer install
