How to fix Error response from daemon: error enabling plugin in Docker

DockerINTERMEDIATEMEDIUM

This error occurs when Docker cannot enable a plugin due to permission issues, missing dependencies, incompatible versions, or plugin configuration problems. The fix typically involves checking plugin requirements, ensuring proper permissions, and verifying Docker daemon compatibility.

What this error means

When you run `docker plugin enable` or install a plugin that auto-enables, Docker attempts to start the plugin's runtime environment. If the plugin cannot be initialized, Docker returns this error from the daemon. Docker plugins extend the Docker Engine's functionality, providing volume drivers, network drivers, authorization handlers, and other features. Each plugin runs as a separate process managed by the Docker daemon. When enabling fails, it typically means the plugin cannot access required resources, lacks necessary permissions, or has configuration issues. This error commonly appears when installing storage plugins (like rexray or local-persist), network plugins, or logging drivers. The underlying cause varies significantly depending on the specific plugin type and system configuration.

How to fix "Error response from daemon: error enabling plugin"

1Check Docker daemon logs for detailed error

The generic error message often hides the real cause. Check the Docker daemon logs for specifics:

bash

# On systemd-based systems (Ubuntu, Debian, CentOS 7+)
sudo journalctl -u docker.service --since "5 minutes ago" | grep -i plugin

# Or check the daemon log directly
sudo tail -100 /var/log/docker.log | grep -i plugin

Look for messages mentioning the plugin name, permission denied, or missing files.

2Inspect the plugin configuration

Review the plugin's current configuration and required permissions:

bash

docker plugin inspect <plugin-name>

Pay attention to:
- Settings.Devices: Required device access (e.g., /dev/fuse)
- Settings.Mounts: Required mount points
- Config.Network.Type: Network requirements (host, bridge)
- Config.Linux.Capabilities: Required Linux capabilities

Example for a storage plugin:

json

{
  "Settings": {
    "Devices": [{"Path": "/dev/fuse"}],
    "Mounts": [{"Source": "/var/lib/plugin-data", "Destination": "/data"}]
  }
}

3Verify required capabilities are granted

When installing plugins, Docker prompts for capability grants. If you skipped this or the plugin needs different capabilities:

bash

# Disable the plugin first
docker plugin disable <plugin-name>

# Re-enable with capability grant
docker plugin set <plugin-name> <capability>=<value>

# Or remove and reinstall with grants
docker plugin rm <plugin-name>
docker plugin install <plugin-name> --grant-all-permissions

Warning: Only use --grant-all-permissions for trusted plugins, as it grants extensive host access.

4Ensure required host directories exist

Many plugins require specific directories on the host. Create them if missing:

bash

# Check what mounts the plugin needs
docker plugin inspect <plugin-name> --format '{{.Settings.Mounts}}'

# Create required directories
sudo mkdir -p /var/lib/<plugin-data-dir>
sudo chmod 755 /var/lib/<plugin-data-dir>

For storage plugins, the data directory is often configurable:

bash

docker plugin set <plugin-name> DATA_DIR=/custom/path

5Check device availability

Some plugins require specific devices. For example, FUSE-based storage plugins need /dev/fuse:

bash

# Check if device exists
ls -la /dev/fuse

# If missing, load the fuse module
sudo modprobe fuse

# Make it persistent across reboots
echo "fuse" | sudo tee /etc/modules-load.d/fuse.conf

For other devices, check docker plugin inspect output and ensure they exist.

6Verify Docker version compatibility

Check the plugin documentation for Docker version requirements:

bash

# Check your Docker version
docker version

# Check plugin API version
docker plugin inspect <plugin-name> --format '{{.Config.Interface.Types}}'

If the plugin requires a newer Docker version, upgrade Docker or use an older plugin version:

bash

docker plugin install <plugin-name>:<version-tag>

7Reinstall the plugin completely

If configuration changes don't help, perform a clean reinstall:

bash

# Force disable if it has references
docker plugin disable -f <plugin-name>

# Remove the plugin
docker plugin rm <plugin-name>

# Clean any leftover state (plugin-specific)
sudo rm -rf /var/lib/docker/plugins/<plugin-id>

# Reinstall with explicit grants
docker plugin install <plugin-name> --grant-all-permissions

Then try enabling:

bash

docker plugin enable <plugin-name>

8Restart Docker daemon

Sometimes the daemon needs a restart to properly initialize plugin infrastructure:

bash

sudo systemctl restart docker

# Verify daemon is running
sudo systemctl status docker

# Try enabling the plugin again
docker plugin enable <plugin-name>

Check that the plugin appears enabled:

bash

docker plugin ls
