Troubleshooting

Configuration issues

If you have errors related to configuration issues, see the warning at step 4 in the configure node deployment section.

Process binding issue

If you need to restart, make sure you kill any hanging db processes with the following commands.

Info

You can find the port number from the log warnings.

sudo lsof -t -i:<DB_PORT>
kill -9 <PID>

Kill all Docker containers and images

You can fix many restart issues and persistent errors by stopping and deleting all Docker containers and images.

docker rm $(docker ps -aq)
docker rmi $(docker images -q)
