Hi Everybody,
I'm switching from Docker to Podman on my VPS and I'm trying to convert all
docker-compose to Pod Yaml.
I know that Podman is supposed to use for `podman play kube` only Yaml generated by
`podman generate kube` and not user generated Yaml. But it works just fine like for
example demonstrated here: https://www.redhat.com/sysadmin/compose-podman-pods
I found project `Kompose` and I know that Podman 3.0 is supposed to support actual
docker-compose but it's very clear to me that Pod Yaml is the right way to go.
The only thing I can't reproduce in Pod Yaml is `build: .` like this:
--------------------------
version: '3'
services:
web:
build: .
...
db:
image: mariadb
...
--------------------------
In other words this will not work:
--------------------------
apiVersion: v1
kind: Pod
metadata:
labels:
app: my-pod
name: my-pod
status: {}
spec:
restartPolicy: Always
containers:
- name: web
build: .
...
- name: db
image: mariadb
...
--------------------------
So the only way is to create `Containerfile`, `podman build .` and then define Yaml like
this:
--------------------------
apiVersion: v1
kind: Pod
metadata:
labels:
app: my-pod
name: my-pod
status: {}
spec:
restartPolicy: Always
containers:
- name: web
image: sha256:307e5ce57d57472b6392f5027e0aa69c1090cd312e3429afdbd950d0d1fbae15
...
- name: db
image: mariadb
...
--------------------------
Could you please tell me is there a way how to build image from Pod Yaml like you can do
with docker-compose?
Thank you.
Kind regards,
