Understanding docker

docker pull couchdb

docker run -d couchdb

Nothing in, nothing out!

docker run -d -p 5984:5984 couchdb

CouchDB! Add some data. And restart the computer. No more couchDB 😞

docker run -d -p 5984:5984 couchdb

No more data. 😭

docker ps -a
docker stop <BAD CONTAINER NAME>
docker start <GOOD CONTAINER NAME>

Yay! My data.

Time to clean:

docker system df
docker ps -a
docker rm <UNUSED CONTAINERS>
