I am new to kubernetes. Recently set up kubernetes cluster with 1 master and 1 node.
I am able to start a docker container by running
sudo docker run <docker-image>
in my node machine.
But i failed to start docker container as a pod using kubernetes yml file.
by running sudo kubectl create -f deployment.yml
I describe the pod information and saw this error message.
Last State: Terminated
Reason: ContainerCannotRun
Message: OCI runtime create failed: container_linux.go:345: starting container process caused "exec: \"HOSTNAME\": executable file not found in $PATH": unknown
Exit Code: 128
docker container supposes to start a java executable. this is my deployment file
kind: Service
apiVersion: v1
metadata:
name: service1-service
spec:
selector:
app: service1
ports:
- protocol: "TCP"
# Port accessible inside cluster
port: 26666
# Port to forward to inside the pod
targetPort: 26666
# Port accessible outside cluster
nodePort: 26666
type: LoadBalancer
---
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
name: service1-depolyment
spec:
selector:
matchLabels:
app: service1
replicas: 1
template:
metadata:
labels:
app: service1
spec:
containers:
- name: service1
image: service1-docker-image
imagePullPolicy: Never
ports:
- containerPort: 26666
# args: ["HOSTNAME", "KUBERNETES_PORT"]
In this deployment file, I try to create a nginx and one java web applicaition service.
It is because i defined wrong apiVersion and kind ?
Any help would be appreciated.
Look at this error exec: \"HOSTNAME\": executable file not found in $PATH
I had a similar error since the container could not locate the docker "CMD" binary since I gave it the wrong path. Check the path to the file and that should do the trick.
