Symptoms / Initial Diagnosis

The following symptoms triggered this RCA:

• The pod is in a Pending state and the container is stuck in ContainerCreating. The events show repeated 'FailedMount' errors because the 'missing-secret-does-not-exist' Secret, which is mounted as a volume, cannot be found.

---

Root Cause

The pod is failing to start because it's trying to mount a Secret named 'missing-secret-does-not-exist' that does not exist in the cluster.

Confidence: 85%

---

Evidence

• The pod's describe output (Step 1) shows that the pod is in a Pending state and the container is stuck in ContainerCreating.
• The 'missing-secret-volume' is configured to mount the 'missing-secret-does-not-exist' Secret, and since that Secret doesn't exist, the mount fails and the pod cannot start.
• Step 2 confirms the 'missing-secret-does-not-exist' Secret does not exist.
• The pod events also showed 'FailedMount' errors due to the missing Secret.

---

Remediation Options

Option A

Create the missing Secret

Low Risk | Quick

Create the 'missing-secret-does-not-exist' Secret in the 'instavote' namespace. You can create an empty Secret if the pod doesn't actually need it, or populate it with the required data.

Command:

kubectl create secret generic missing-secret-does-not-exist -n instavote

---

Option B

Remove the volume mount

Low Risk | Moderate

Remove the 'missing-secret-volume' volume and corresponding mount from the pod specification if the pod does not actually need access to this secret.

Command:

kubectl edit pod configmap-mount-test-d449d85b9-xqx2b -n instavote

---

Option C

Modify the deployment to remove the volume mount

Low Risk | Moderate

Remove the 'missing-secret-volume' volume and corresponding mount from the deployment specification if the pod does not actually need access to this secret. This is the preferred approach as it ensures all future pods created by the deployment do not attempt to mount the non-existent secret.

Command:

kubectl edit deployment configmap-mount-test -n instavote

[OK] Planning

Plan generated: The pod is failing to start due to a FailedMount error, specifically because a Secret it depends on does not exist.
