+# Docker containers
+
+## `docker run`
+
+* `--rm` will remove the Docker container after running the command (otherwise
+ have to do it manually if you want to run another one-shot command)
+* `-v <local path>:<container path>`: mount a volume
+* `--entrypoint <command>`: use custom entry point, not from Dockerfile. Specify
+ just the command, give arguments after specifying image.
+
+## `docker exec`
+
+Runs a command against a *running* container.
