// Custom error class for when the Docker image is not found locally/remotely
// This can happen when using the "n8nio/n8n:local" image, which is not available on Docker Hub
// This image is available after running `pnpm build:docker` at the root of the repository
export class DockerImageNotFoundError extends Error {
constructor(containerName: string, originalError?: Error) {
const dockerImage = process.env.N8N_DOCKER_IMAGE ?? 'n8nio/n8n:local';
const message = `Failed to start container ${containerName}: Docker image '${dockerImage}' not found locally!
This is likely because the image is not available locally.
To fix this, you can either:
1. Build the image by running: pnpm build:docker at the root
2. Use a different image by setting: N8N_DOCKER_IMAGE=<image-tag>
Example with different image:
N8N_DOCKER_IMAGE=n8nio/n8n:latest npm run stack`;
super(message);
this.name = 'DockerImageNotFoundError';
this.cause = originalError;
}
}
