Troubleshooting

I'm seeing a Python traceback when running docker-compose

The output you see looks similar to

Traceback (most recent call last):
File "urllib3/connectionpool.py", line 670, in urlopen
File "urllib3/connectionpool.py", line 392, in _make_request
File "http/client.py", line 1255, in request
File "http/client.py", line 1301, in _send_request
File "http/client.py", line 1250, in endheaders
File "http/client.py", line 1010, in _send_output
File "http/client.py", line 950, in send
File "docker/transport/unixconn.py", line 43, in connect
FileNotFoundError: [Errno 2] No such file or directory

Those errors are usually encountered when the docker service is not running on your machine.

I'm using docker compose with sudo and the environment variables are not set

sudo runs commands as a different user and doesn't preserve the original user's environment unless run using the --preserve-env flag. With that said, nowadays docker and docker compose is commonly packaged such that it doesn't require sudo for execution. That's why our examples don't display the usage of sudo.

I'm using an .env file and the variables are not properly set

You've likely pasted the environment variables with a leading export command from our shell example snippet. Shell commands don't work in .env files and need to be omitted.

I'm getting the unhelpful 'Killed' error message

Your machine has run out of memory while starting the containers. Consider using a more powerful instance. 1GB is a minimum that is known to work.

I'm seeing error messages in the SeaweedFS Container

At the start, the SeaweedFS container repeatedly shows two error messages in the log (RPC error and missing pemfile). Both can safely be ignored when using the reference deployment as they are triggered by its internal service being started while polling on each other.

I'm unable to log in to the registry: 'Cannot autolaunch D-Bus'

Docker needs something to store your credentials in. On Linux this is pass. If this is not installed you might see this error:

Error saving credentials: error storing credentials - err: exit status 1, out: `Cannot autolaunch D-Bus without X11 $DISPLAY`

Simply install pass to resolve this issue.

'Invalid parameter: redirect_uri' error when trying to log in

This error originates from Keycloak and indicates a missing or erroneous configuration of Keycloak. Keycloak should be configured following this guide. If the error persists or the configuration has been set already then the valid redirect URIs should be inspected for typos.
