I want to deploy IBM-MQ to Kubernetes (Rancher) using helmfile. I've found this link and did everything as described in the guide: https://artifacthub.io/packages/helm/ibm-charts/ibm-mqadvanced-server-dev.
But the pod is not starting with the error: "ImagePullBackOff". What could be the problem? My helmfile:
...
repositories:
- name: ibm-stable-charts
url: https://raw.githubusercontent.com/IBM/charts/master/repo/stable
releases:
- name: ibm-mq
namespace: test
createNamespace: true
chart: ibm-stable-charts/ibm-mqadvanced-server-dev
values:
- ./ibm-mq.yaml
ibm-mq.yaml:
- - -
license: accept
security:
initVolumeAsRoot: true/false // I'm not sure about this, I added it just because it wasn't working.
// Both of the options don't work too
queueManager:
name: "QM1"
dev:
secret:
adminPasswordKey: adminPassword
name: mysecret
I've created the secret and seems like it's working, so the problem is not in the secret. The full error I'm getting:
Failed to pull image "ibmcom/mq:9.1.5.0-r1": rpc error: code = Unknown desc = Error response from daemon: manifest for ibmcom/mq:9.1.5.0-r1 not found: manifest unknown: manifest unknown
I'm using helm 3, helmfile v.0.141.0, kubectl 1.22.2
I will leave some things as an exercise to you, but here is what that tutorial says:
helm repo add ibm-stable-charts https://raw.githubusercontent.com/IBM/charts/master/repo/stable
You don't really need to do this, since you are using helmfile.
Then they say to issue:
helm install --name foo
ibm-stable-charts/ibm-mqadvanced-server-dev
--set license=accept
--set queueManager.dev.secret.name=mysecret
--set queueManager.dev.secret.adminPasswordKey=adminPassword
--tls
which is targeted towards helm2 (because of those --name and --tls), but that is irrelevant to the problem.
When I install this, I get the same issue:
Failed to pull image "ibmcom/mq:9.1.5.0-r1": rpc error: code = NotFound desc = failed to pull and unpack image "docker.io/ibmcom/mq:9.1.5.0-r1": failed to resolve reference "docker.io/ibmcom/mq:9.1.5.0-r1": docker.io/ibmcom/mq:9.1.5.0-r1: not found
I went to the docker.io page of theirs and indeed such a tag : 9.1.5.0-r1 is not present.
OK, can we update the image then?
helm show values ibm-stable-charts/ibm-mqadvanced-server-dev
reveals:
image:
# repository is the container repository to use, which must contain IBM MQ Advanced for Developers
repository: ibmcom/mq
# tag is the tag to use for the container repository
tag: 9.1.5.0-r1
good, that means we can change it via an override value:
helm install foo
ibm-stable-charts/ibm-mqadvanced-server-dev
--set license=accept
--set queueManager.dev.secret.name=mysecret
--set queueManager.dev.secret.adminPasswordKey=adminPassword
--set image.tag=latest # or any other tag
so this works.
How to set-up that tag in helmfile is left as an exercise to you, but it's pretty trivial.
