Initcontainer command in kubernetes challange 1 is erring out

venumadhav.hari · January 28, 2023, 10:45pm

No matter how I write the initContainer command in Kubernetes challange 1, I see the task as incomplete.

Here is my POD configuration.

apiVersion: v1
kind: Pod
metadata:
name: jekyll
labels:
run: jekyll
spec:
initContainers:

name: copy-jekyll-site
image: kodekloud/jekyll
command: [‘sh’, ‘-c’, “jekyll new /site”]
volumeMounts:
- name: site
  mountPath: /site
  containers:
name: jekyll
image: kodekloud/jekyll-serve
volumeMounts:
- name: site
  mountPath: /site
  volumes:
- name: site
  persistentVolumeClaim:
  claimName: jekyll-site

I tried with command: [ “jekyll”, “new”, “/site”]. That too was not accepted. Where am I going wrong?

Hi @venumadhav.hari
You add container information inside initContainers base on the YAML file you provide. The right syntax should be :

apiVersion: v1
kind: Pod
metadata:
  namespace: development
  name: jekyll
  labels:
    run: jekyll
spec: 
  containers:
  - name: jekyll
    image: kodekloud/jekyll-serve
    volumeMounts:
    - mountPath: /site
      name: site  
  initContainers:
  - name: copy-jekyll-site
    image: kodekloud/jekyll
    command: [ "jekyll", "new", "/site" ]
    volumeMounts:
    - mountPath: /site
      name: site
  volumes:
  - name: site
    persistentVolumeClaim:
      claimName: jekyll-site

You need to create a block container

Hi @mmkmou,
Thanks for the reply.
The error in my Yaml was a copy paste indentation error.

However, I have tried the same exact way that you have mentioned in your yaml. But still I got the same error.

Thanks,
Venu

Hi @venumadhav.hari,
Can you please provide us the copy - paste of your error?

I have the same issue, I have all task green except for the pod and the only issue is the command

apiVersion: v1
kind: Pod
metadata:
  name: jekyll
  namespace: development
  labels:
    run: jekyll
spec:
  containers:
  - name: jekyll
    image: kodekloud/jekyll-serve
    volumeMounts:
    - name: site
      mountPath: /site
  initContainers:
  - name: copy-jekyll-site
    image: kodekloud/jekyll
    command: [ "jekyll", "new", "/site" ]
    volumeMounts:
    - name: site
      mountPath: /site
  volumes:
    - name: site
      persistentVolumeClaim:
        claimName: jekyll-site

Thanks

Hi @deanholmes @venumadhav.hari

Just tested the challenge and its work fine

deanholmes · May 16, 2023, 10:05pm

Then I’m more confused.
Any ideas?

mmkmou · May 16, 2023, 10:10pm

Please try again and be sure that the pod is running

deanholmes · May 17, 2023, 5:24pm

Hi,

I now have multiple attempts at this, the pod is running but I still get the x at the command

I don’t know what I did different but it finally completed, it might be a timing thing, giving it enough time to complete the command
I’m going to run it a few more times just to practice

Thanks
Dean

The issue is the git lab code. if you directly copypaste or clone the gitlab , then that code will give issue of command run and init container not running.
After multiple tries , finally create a dummy pod using --dry-run=client and saving it to yaml file.

k run pod --image gcr.io/kodekloud/customimage/jekyll-serve -l run=jekyll -n development --dry-run=client -o yaml > jekyll_pod.yaml

after that editing the file to add line by line all stuff.
make sure you type everything and use proper indentation.
after completing file, you will notice no change from gitlab file but still this will not give error coz we typed and not copy pasted.

vi jekyll_pod.yaml
rm -rf /site
