Rootless Docker (Basic)
You can manage Docker containers without needing sudo
systemctl --user: This command manages systemd user services. Rootless Docker often uses systemd for managing its services within your user session.
Start:
systemctl --user start docker.socket
systemctl --user start docker.service
Verify Docker is Running: docker info
docker ps --Lists currently running Docker containers.
docker ps -a --Lists all Docker containers (running and stopped).
docker images --Lists downloaded Docker images.
docker pull image_name --Downloads a Docker image from a registry (like Docker Hub).
docker run image_name --Creates and starts a Docker container from an image. You'll often need to specify ports and volumes.
docker run -d --name my_container -p 8080:80 nginx --Runs an Nginx container in the background (-d), names it my_container, and maps port 8080 on the host to port 80 in the container.
docker stop container_id_or_name --Stops a running Docker container.
docker start container_id_or_name --Starts a stopped Docker container.
docker restart container_id_or_name --Restarts a Docker container.
docker rm container_id_or_name --Removes a stopped Docker container.
docker rmi image_name --Removes a Docker image. Use with caution!
Set Environment Variables (If Necessary)
echo $DOCKER_HOST
If it's not set or you encounter issues, you might need to set it manually. Consult the rootless Docker documentation or the output of your installation.
