Hey @chandan988, this sounds like docker compose didn’t understand your docker compose file. Is there a chance you have any unsupported or missing characters, missing indentation and the likes in there? You can find a simple example of a valid docker compose file [here](https://github.com/n8n-io/n8n/blob/master/docker/compose/withPostgres/docker-compose.yml). A slightly more complex example also including a web server would be [here in our documentation](https://docs.n8n.io/getting-started/installation/advanced/server-setup.html#docker-compose-example). ---

Hey @chandan988, could you share your `docker-compose.yml` file so we can take a look at what might be wrong with it? ---

Hey @chandan988, Looking at the video the first thing I noticed was when you copied the .env file content it didn’t appear to comment out the first line and the # was missing. Can you add that in and see if it changes anything, Can you also tell me what version of Docker Compose you are running? ---

Hey @chandan988, What about the version of Docker Compose? I ran the YAML you pasted through a validator and it comes up as valid. Is it possible that something went wrong when pasting the YAML? As a test could you save the file locally and upload it using SFTP to your instance that would help rule out anything odd.
