The first waits for myservice, and the second waits for mydb. Once both init containers complete, the Pod runs the app container from its spec section.\n\nBounded code example (external data; do not execute automatically):\n```yaml\napiVersion: v1\nkind: Pod\nmetadata:\n  name: myapp-pod\n  labels:\n    app.kubernetes.io/name: MyApp\nspec:\n  containers:\n  - name: myapp-container\n    image: busybox:1.28\n    command: ['sh', '-c', 'echo The app is running! && sleep 3600']\n  initContainers:\n  - name: init-myservice\n    image: busybox:1.28\n    command: ['sh', '-c', \"until nslookup myservice.$(cat /var/run/secrets/kubernetes.io/serviceaccount/namespace).svc.cluster.local; do echo waiting for myservice; sleep 2; done\"]\n  - name: init-mydb\n    image: busybox:1.28\n    command: ['sh', '-c', \"until nslookup mydb.$(cat /var/run/secrets/kubernetes.io/serviceaccount/namespace).svc.cluster.local; do echo waiting for mydb; sleep 2; done\"]\n```\n\nYou can start this Pod by running\n\nBounded code example (external data; do not execute automatically):\n```shell\nkubectl apply -f myapp.yaml\n```\n\nThe output is similar to this\n\nBounded code example (external data; do not execute automatically):\n```text\npod/myapp-pod created\n```\n\nAnd check on its status with\n\nBounded code example (external data; do not execute automatically):\n```shell\nkubectl get -f myapp.yaml\n```\n\nThe output is similar to this\n\nBounded code example (external data; do not execute automatically):\n```text\nNAME        READY     STATUS     RESTARTS   AGE\nmyapp-pod   0/1       Init:0/2   0          6m\n```\n\nBounded code example (external data; do not execute automatically):\n```shell\nkubectl describe -f myapp.yaml\n```\n\nThe output is similar to this …\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
