Issue

When attempting to uninstall the Dispatcher Tools deployed on Linux, the cache directory can’t be deleted due to insufficient permissions.

# rm -fr dispatcher-sdk-2.0.235/
rm: cannot remove 'dispatcher-sdk-2.0.235/cache/html': Permission denied

Resolution resolution

In the Dispatcher Tools, Docker creates the cache/html directory with Apache user’s ownership (displayed as 100:101).

$ ls -ltr dispatcher-publish:2.0.235/cache
total 4
drwxr-x---. 2 100 101 4096 Jan 1 00:00 html

$ docker ps

There are two available methods to uninstall the Dispatcher Tools:

Method 1 - Uninstall using root privileges

# rm -fr dispatcher-sdk-2.0.235

Method 2 - Uninstall by a non-root user

While the Dispatcher Tools are still running, delete the /mnt/var/www/html directory from inside of the Docker container. Then stop the container and uninstall the Dispatcher Tools.

Example:

$ docker exec -it 9fe753063799 rm -rf /mnt/var/www/html
$ docker stop 9fe753063799
$ rm -fr dispatcher-sdk-2.0.235
