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. A slightly more complex example also including a web server would be here in our documentation.

ERROR: yaml.parser.ParserError: while parsing a block mapping

in “./docker-compose.yml”, line 4, column 9

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?

Still Same error

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.
