I want my deployment setup to use an image that was the result of an assembly configuration.
I am currently using something like this:
- apiVersion: v1
kind: DeploymentConfig
metadata:
annotations:
openshift.io/generated-by: OpenShiftNewApp
creationTimestamp: null
labels:
app: myapp
name: myapp
spec:
replicas: 1
selector:
app: myapp
deploymentconfig: myapp
strategy:
resources: {}
template:
metadata:
annotations:
openshift.io/container.myapp.image.entrypoint: '["python3"]'
openshift.io/generated-by: OpenShiftNewApp
creationTimestamp: null
labels:
app: myapp
deploymentconfig: myapp
spec:
containers:
- name: myapp
image: 123.123.123.123/myproject/myapp-staging:latest
resources: {}
command:
- scripts/start_server.sh
ports:
- containerPort: 8000
test: false
triggers: []
status: {}
I had to hardcode the integrated docker registry IP address; otherwise Kubernetes / OpenShift will not be able to find the snapshot. I would not like to hardcode the integrated IP address of the docker registry, but instead use something like this:
- apiVersion: v1
kind: DeploymentConfig
metadata:
annotations:
openshift.io/generated-by: OpenShiftNewApp
creationTimestamp: null
labels:
app: myapp
name: myapp
spec:
replicas: 1
selector:
app: myapp
deploymentconfig: myapp
strategy:
resources: {}
template:
metadata:
annotations:
openshift.io/container.myapp.image.entrypoint: '["python3"]'
openshift.io/generated-by: OpenShiftNewApp
creationTimestamp: null
labels:
app: myapp
deploymentconfig: myapp
spec:
containers:
- name: myapp
from:
kind: "ImageStreamTag"
name: "myapp-staging:latest"
resources: {}
command:
- scripts/start_server.sh
ports:
- containerPort: 8000
test: false
triggers: []
status: {}
But this makes Kubernetes / OpenShift complain about:
The DeploymentConfig "myapp" is invalid.
spec.template.spec.containers[0].image: required value
How can I specify assembly configuration output as an image for use in deployment configuration?
Thank you for your time!
