This project is to demonstrate different ways to set containers to run using the Docker Restart Policy. Good times.

Run:

docker build -t test-restart .

Then:

docker run --name testing-restarts testing-restart

Then run this on repeat until you see the container has exited (10 seconds):

docker ps -a

Clearly we can see the container stops running. But if we run it with this:

docker run --name testing-restarts --restart always testing-restart

We see after 10 seconds the container fails then runs again because docker restarted it.

However, if you want to just have it restart unless you have a real problem better to run with this;

docker run --name testing-restarts --restart unless-stopped testing-restart
