Remove Docker Images Older Than One week/month/year Automatically
Reason
I’m using rancher pipelines to deploy my service immediately after I push my code to GitHub, it always creates a new image but would never clean it.
I guess other continuous integration solutions would do the same.
Next, I’m going to share some lines of code on how to deal with it.
Steps
Let’s say the project I’m going to build is named GetShitDone.
The way to clear old images is as simple as copy and paste the codes below.
The images that are still in use would be protected and wouldn’t be removed.
It’s safe to use these commands.
Remove images older than one week
1 | project_name=GetShitDone |
If you would like to keep the images for months or longer, you can remove the weeks ago
and months ago
part.
Only remove images earlier than one month
1 | project_name=GetShitDone |
And clean images created one year ago
1 | project_name=GetShitDone |
That’s all of it, cheers.
