This behavior is illustrated in the following example.\n\nCreate a Dockerfile that prints the numbers 1 to 5 and then exits.\n\nBounded code example (external data; do not execute automatically):\n```dockerfile\n   FROM busybox:latest\n   COPY --chmod=755 <<\"EOF\" /start.sh\n   echo \"Starting...\"\n   for i in $(seq 1 5); do\n     echo \"$i\"\n     sleep 1\n   done\n   echo \"Exiting...\"\n   exit 1\n   EOF\n   ENTRYPOINT /start.sh\n```\n\nBuild an image from the Dockerfile.\n\nBounded code example (external data; do not execute automatically):\n```console\n   $ docker build -t startstop .\n```\n\nRun a container from the image, specifying always for its restart policy.\n\nThe container prints the numbers 1..5 to stdout, and then exits. This causes the attached CLI to exit as well.\n\nBounded code example (external data; do not execute automatically):\n```console\n   $ docker run --restart always startstop\n   Starting...\n   1\n   2\n   3\n   4\n   5\n   Exiting...\n   $\n```\n\nRunning docker ps shows that is still running or restarting, thanks to the restart policy. The CLI session has already exited, however. It doesn't survive the initial container exit.\n\nBounded code example (external data; do not execute automatically):\n```console\n   $ docker ps\n   CONTAINER ID   IMAGE       COMMAND                  CREATED         STATUS         PORTS     NAMES\n   081991b35afe   startstop   \"/bin/sh -c /start.sh\"   9 seconds ago   Up 4 seconds             gallant_easley\n```\n\nYou can re-attach your terminal to the container between restarts, using the docker container attach command. It's detached again the next time the container exits.\n\nBounded code example (external data; do not execute automatically):\n```console\n   $ docker container attach 081991b35afe\n   4\n   5\n   Exiting...\n   $\n```\n\nAttribution: Adapted from Docker Documentation under Apache-2.0.
