CrashLoopBackOff when args are added in Kubernetes
This deployment is fine until I add args (added below) to the deployment. I can’t figure out why it would turn into a CrashLoopError when adding simple args. I even tried to echo Hello World and it still results in a CrashLoopError.
There are no logs and when I describe the pod it shows:
Warning FailedSync Error syncing pod, skipping: failed to "StartContainer" for "nginx" with CrashLoopBackOff: "Back-off 10s restarting failed container=nginx pod=nginx-2247906467-r9znh_dave-testing(98c3999e-c39b-11e6-936e-0050568b4a68)"
and here is the YAML:
- kind: Deployment apiVersion: extensions/v1beta1 metadata: name: nginx spec: replicas: 1 template: metadata: labels: name: nginx version: "1.9" spec: containers: - name: nginx imagePullPolicy: Always image: "nginx:1.9" ports: - containerPort: 80 args: - "echo $NGINX_CONF > /etc/nginx/nginx.conf" env: - name: NGINX_CONF valueFrom: secretKeyRef: name: confs key: nginx

Here is a working version of Kubernetes Pod with nginx alpine docker image:
apiVersion: v1 kind: Pod metadata: name: frontend-nginx-pod labels: app: nginx-test spec: containers: - name: nginx image: nginx:1.11.6-alpine ports: - containerPort: 80 name: "http-server" args: - /bin/sh - -c - echo "hello" > /usr/share/nginx/html/index.html && nginx "-g daemon off;"
I was getting the same error without listing
args as above.
