Docker Deployment

Big Picture

The big picture of what we are doing is taking the app and deploying it to a server. This happens by:

• Building the Docker image locally from source code
• Pushing the locally built image, latest, to the Docker Cloud account
• Logging into the server through SSH
• Once on the server, we download the latest docker built from the Docker Cloud account
• Once we have the latest image we use docker-compose to start the containers that house the latest image we built

What you need

• Docker installed
• A Docker account
• An invitation to the labbee/wildland Docker Cloud account
• The password for SSH

Useful Docker commands when on the server

docker attach <sha>

• see container output

docker exec -it <sha> /bin/sh

• terminal instance for the container

docker ps

• list running containers

docker images

• list downloaded images

docker-compose up -d

• start containers from docker-compose.yml

docker-compose down

• stop containers from docker-compose.yml

docker container inspect <sha>

• shows data for the container

docker stop <sha>

• stops a container
