Subject: [PATCH] [podman] Simplify the code for checking if an image exists
|
|
|
9cf66a |
|
|
|
9cf66a |
Let's switch to the existing 'podman image exists' to determine if
|
|
|
9cf66a |
an image is local to the machine or if it needs pulling.
|
|
|
9cf66a |
|
|
|
9cf66a |
Let's change this for a number of reasons:
|
|
|
9cf66a |
- It simplifies the code greatly
|
|
|
9cf66a |
- It makes everything work even when the image is prefixed with 'localhost/'
|
|
|
9cf66a |
names which are not detected as local images
|
|
|
9cf66a |
- It makes the code faster as we do not need to list all the images as
|
|
|
9cf66a |
that is more expensive
|
|
|
9cf66a |
|
|
|
9cf66a |
Tested by running a couple of full containerized OpenStack deployments,
|
|
|
9cf66a |
one with images tagged as 'localhost/foo/mysql:pcmklatest' and one
|
|
|
9cf66a |
with a normal registry host prefix.
