Lab Solution

You can run a command inside the container to list files:

docker exec tls ls /certs

The docker cp command copies files between containers and the local filesystem.

To copy from the container called tls, use:

docker cp tls:/certs/server-cert.pem .

docker cp tls:/certs/server-key.pem .

You can also copy from the local machine into the container, but the target path needs to exist:

docker exec tls mkdir /certs-backup

docker cp server-cert.pem tls:/certs-backup/

docker cp server-key.pem tls:/certs-backup/

docker exec tls ls /certs-backup
