Does 'docker start' execute the CMD command?

Let's say a docker container has been run with docker run and then stopped with docker stop. Will the CMD command be executed after a docker start?

I believe @jripoll is incorrect, it appears to run the command that was first run with docker run on docker start too.

Here's a simple example to test:

First create a shell script to run called tmp.sh:

echo "hello yo!"

Then run:

docker run --name yo -v "$(pwd)":/usr/src/myapp -w /usr/src/myapp ubuntu sh tmp.sh 

That will print hello yo!.

Now start it again:

docker start -ia yo

It will print it again every time you run that.

Same thing with Dockerfile

Save this to Dockerfile:

FROM alpine

CMD ["echo", "hello yo!"]

Then build it and run it:

docker build -t hi .
docker run -i --name hi hi

You'll see "hello yo!" output. Start it again:

docker start -i hi

And you'll see the same output.
