Canasta: Using Canasta > Troubleshooting

This page covers common troubleshooting steps for Canasta installations.

Checking container status

To see if your Canasta containers are running:

cd /path/to/installation
sudo docker compose ps

To view logs from the web container:

cd /path/to/installation
sudo docker compose logs web

To follow logs in real-time:

sudo docker compose logs -f web

To view logs from all containers:

sudo docker compose logs

To connect to the MySQL database directly:

cd /path/to/installation
sudo docker compose exec db mysql -u root -p

Enter the root database password from your .env file when prompted.

To run arbitrary commands inside the web container:

cd /path/to/installation
sudo docker compose exec web <command>

For example, to check PHP version:

sudo docker compose exec web php -v

To get a shell inside the container:

sudo docker compose exec web bash

Installation fails with "Canasta installation with the ID already exists"

An installation with that ID is already registered. Use canasta list to see existing installations, or choose a different ID.
