Learn what restart policies do and how to use them
|
||
|
|
|
||
|
|
### Requirements
|
||
|
|
|
||
|
|
Make sure Docker is installed on your system and the service is started
|
||
|
|
|
||
|
|
```
|
||
|

# Fedora/RHEL/CentOS
|
||

rpm -qa | grep docker

### Instructions
|
||
|
|
|
||
|
|
1. Run a container with the following properties:
|
||
|
|
* image: alpine
|
||
|
|
* name: forest
|
||
|
|
* restart policy: always
|
||
|
|
* command to execute: sleep 15
|
||
|
|
2. Run `docker container ls` - Is the container running? What about after 15 seconds, is it still running? why?
|
||
|
|
3. How then can we stop the container from running?
|
||
|
|
4. Remove the container you've created
|
||
|
|
5. Run the same container again but this time with `sleep 600` and verify it runs
|
||
|
|
6. Restart the Docker service. Is the container still running? why?
|
||
|
|
8. Update the policy to `unless-stopped`
|
||
|
|
9. Stop the container
|
||
|
|
10. Restart the Docker service. Is the container running? why?
