Docker Exit Code 127

Vad som orsakar detta fel

The binary or script specified in CMD, ENTRYPOINT, or the docker run command does not exist inside the container. The executable may not be installed, the path may be wrong, or a multi-stage build may have missed copying it.

Hur man åtgärdar det

Verify the binary exists in the image: docker run --entrypoint sh image -c 'which myapp'. Check CMD/ENTRYPOINT paths. In multi-stage builds, ensure the binary is copied to the final stage. Install missing dependencies in the Dockerfile.

# Check that CMD/ENTRYPOINT binary exists in the image
docker run --entrypoint sh myimage -c "which myapp"
