docker: run and exec
The following
docker run command creates a
container named
cont-xyz and runs a shell (
/bin/sh) in it:
$ docker run --name cont-abc --rm -i -t busybox /bin/sh
In another shell on the host,
docker exec is used to run another shell in the
same container:
$ docker exec -i -t cont-abc /bin/sh
In one of these created shells, a file is created using
touch:
/ # touch /tmp/touchee
Because the other shell is in the same container, it can see the touched file:
/ # ls -l /tmp/
