Starting Docker in Container Environments
Please check if docker is already installed. If so, to start Docker in a container environment:
# Start Docker daemon in the background
sudo dockerd > /tmp/docker.log 2>&1 &
# Wait for Docker to initialize
sleep 5
On Windows, start Docker Desktop or the Docker service instead of running sudo dockerd; then run Docker commands from PowerShell without sudo.
Verifying Docker Installation
To verify Docker is working correctly, run the hello-world container:
sudo docker run hello-world
PowerShell equivalent after Docker Desktop is running: docker run hello-world.
