All Errors

This error occurs when Docker cannot find the files specified in a COPY instruction during image build. It typically happens due to incorrect build context, .dockerignore rules, or multi-stage build configuration issues.

This error occurs when attempting to execute commands on a stopped Docker container. The container exists but is not in a running state, preventing operations like exec, logs, or attach from working.

This error occurs when a container image reference has invalid format.

Error when image pull repeatedly fails

This error occurs when apt-get cannot find a package in its cache during Docker image builds. The most common cause is missing apt-get update before installation commands.

This error occurs when Docker detects an existing prune operation lock, often caused by interrupted SSH sessions, unresponsive containers, or containerd communication failures.

The Kubernetes scheduler cannot place a pod on any node because resource constraints, node selectors, taints, or infrastructure issues prevent valid placement. Pods remain in Pending state indefinitely. Fix by scaling the cluster, relaxing scheduling constraints, or ensuring nodes have required labels and resources.

Error when Ingress controller cannot reach backend

A Kubernetes webhook connection refused error occurred. This typically indicates a configuration issue, resource constraint, or system problem. Review the error logs, check resource availability, and verify cluster configuration to resolve.

The 503 Service Unavailable error occurs when Docker cannot reach a registry (Docker Hub or private). This is typically caused by registry outages, network issues, or proxy/firewall misconfigurations.

This kubectl authentication error occurs when your client cannot successfully authenticate with the Kubernetes API server. Causes include expired tokens, invalid kubeconfig credentials, IAM role mismatches, or expired certificates.

This error occurs when git stash pop or git stash apply tries to reapply stashed changes that conflict with modifications made to your working directory since the stash was created. The conflict must be resolved manually before you can continue.

A PVC has entered the Lost phase, meaning it lost its binding to the underlying PersistentVolume. This is a critical error indicating data may be inaccessible or lost. It occurs when the PV is deleted while PVC still references it, storage backend fails, or finalizers block cleanup. Recovery is difficult; prevention through backups is essential.

A Docker container that exits with code 0 immediately after starting has successfully completed its main process. This typically occurs when the container's entrypoint or command is a short-lived task rather than a long-running service, or when running interactive shells without proper terminal attachment.

Docker exit code 126 occurs when a command in your container specification is found but cannot be executed. This typically happens when entrypoint scripts or executable files lack proper execute permissions, preventing the container from starting successfully.

Error when Ingress controller pod not running

A container is running but fails health checks, so Kubernetes removes it from service endpoints. Traffic doesn't route to the pod but the container isn't restarted. Fix by increasing initialDelaySeconds, using startup probes, tuning timeouts, or ensuring the application's health endpoint works correctly.

This daemon-level error occurs when Docker cannot write to its storage backend, typically due to Snap installation restrictions, disk space exhaustion, hardware failures, or storage driver issues. The daemon itself fails operations rather than individual containers.

This Python error occurred during execution. Check the error message for details on what went wrong and follow the steps below to diagnose and fix the issue.

A pod fails to pull a container image from a private registry because the registry credentials are missing, incorrect, or the repository doesn't exist. This occurs with private registries (Azure ACR, AWS ECR, etc.) that require authentication. Fix by creating proper imagePullSecrets with correct credentials.
