All Errors

Dynamic PVC provisioning fails due to missing StorageClass, wrong provisioner, or cloud provider issues. Fix by checking StorageClass, verifying provisioner, and checking cloud credentials.

Egress NetworkPolicy rules block pod outbound traffic. Fix by reviewing policy selectors, adding proper egress rules for DNS and external services.

The 'unauthorized: incorrect username or password' error occurs when Docker cannot authenticate with the container registry. This typically happens because you're using your email instead of username, your password contains special characters, or you need to use a Personal Access Token instead of your password.

Service has no ready endpoints because backing pods aren't ready. Fix by checking pod readiness, fixing application health, and verifying endpoint selectors.

EndpointSlice controller can't sync endpoints due to control plane load or permission issues. Fix by checking controller status, RBAC permissions, and control plane health.

EnvoyFilter configuration rejected by Istio control plane due to invalid spec. Fix by validating Envoy configuration, checking Istiod logs, and testing with simple config.

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.

This error occurs when you attempt to stop or kill a Docker container that has already exited. It's a harmless informational message indicating the container is not in a running state and doesn't require stopping.

etcd database full with Kubernetes events. Fix by cleaning up old events, increasing quota, or using separate etcd for events.

This error occurs when a React component attempts to call setState or dispatch a state update while the component is currently rendering. This disrupts React's rendering cycle and can cause infinite loops or unpredictable behavior.

This error occurs when webpack or Metro bundler cannot locate a module during the build process. Common causes include missing dependencies, incorrect import paths, or misconfigured module resolution settings.

The 'Couldn't find env file' error in Docker Compose occurs when the env_file directive references a file that doesn't exist or can't be found. This is typically resolved by creating the missing .env file, correcting the file path, or removing the env_file directive if not needed.

This error occurs when you try to insert or update data that exceeds the maximum length defined for a database column. It's commonly caused by using default String types in MySQL which map to varchar(191) instead of TEXT.

The 'Volume declared as external, but could not be found' error occurs when Docker Compose cannot locate a volume marked as external. External volumes must exist before running docker-compose and are typically created with `docker volume create`. This is resolved by either creating the volume first or removing the external flag to let Compose manage the volume automatically.

The 'removal of container is already in progress' error occurs when Docker is already attempting to delete a container and you try to remove it again. Wait for the operation to complete, or restart Docker if the container is stuck in a zombie state.

The 'No such service' error occurs when Docker Swarm cannot find a service matching the name you specified. This typically happens when the service was never deployed, has been removed, or you're running commands against a non-swarm node. Verify the service exists with docker service ls.

This error occurs when the Docker daemon fails to start on Linux systems using systemd. Common causes include disk space issues, invalid daemon.json configuration, firewall conflicts, or missing dependencies like iptables. Check journalctl logs for the specific cause.

HorizontalPodAutoscaler fails to scale because the metric it references does not exist or is invalid. Metrics may be missing from metrics-server or custom metrics provider.

DNS resolution fails for hostnames from within pods. CoreDNS pods are not running, DNS queries timeout, or upstream DNS is unreachable.

This error occurs when Docker's PID file exists but the daemon isn't properly running, typically after an unclean shutdown, system crash, or when attempting to start Docker while it's already running. The fix involves removing the stale PID file and properly restarting the Docker service.
