How to: Task - Docker image
```Dockerfile
FROM nginx:1.22-alpine
EXPOSE 80
```

Using docker and the Dockerfile above, build an image with tag `bootcamp/nginx:v1` and tag `ckad/nginx:latest`. Once complete, export a tar file of the image to `/home/$USER/ckad-tasks/docker/nginx.tar`. \
Run a container named `web-test` from the image `bootcamp/nginx:v1` accessible on port 2000, and another container named `web-test2` from image `ckad/nginx:latest` accessible on port 2001. Leave both containers running.

What commands would you use to perform the above operations using `podman`? Specify these commands on separate lines in file `/home/$USER/ckad-tasks/docker/podman-commands`
hints
hint 1
You can specify multiple tags when building an image `docker build -t tag1 -t tag2 /path//to/dockerfile-directory`
hint 2
Try to find the command for exporting a docker image with `docker image --help`
hint 2
Did you run the containers in detached mode?
hint 3
You can export a docker image to a tar file with `docker image save -o /path/to/output/file $IMAGE_NAME`
hint 4
Did you expose the required ports when creating the containers? You can use `docker run -p $HOST_PORT:$CONTAINER_PORT`
hint 5
Did you verify the containers running at exposed ports `curl localhost:2000` and `curl localhost:2001`?
hint 6
Docker and Podman have interchangeable commands, therefore, the only change is `docker -> podman`, For example, `docker run -> podman run`, `docker build -> podman build`, etc.
