Urgent! :( My Docker Compose file has stopped working!

Docker Engine Compose
1

I deleted the linux instance and recreated a new instance on the cloud.
I have reinstalled docker and docker compose but when I run the following command I get an error.

docker-compose up -d --build


ERROR: Version in "./docker-compose.yml" is unsupported. You might be seeing this error because you're using the wrong Compose file version. Either specify a supported version (e.g "2.2" or "3.3") and place your service definitions under the `services` key, or omit the `version` key and place your service definitions at the root of the file to use version 1.
For more on the Compose file format versions, see https://docs.docker.com/compose/compose-file/

Why does this happen?
On another instance I have the same version of docker and docker compose and everything works fine.

See you soon and thanks

docker-compose.yml

version: "3.9"

services:

It looks like you are using two different commands. docker-compose could be an older version while docker compose runs the compose plugin of Docker. That version donā€™t even need the version keyword in the compose file. If you just run

docker compose up -d --build

with the space character between docker and compose, that should work.

Amazing. Iā€™m not sure what drew me to this post, but I had no idea there was a docker compose pluginā€¦

I cannot mark the answer above as a solution, the icon does not appear.

You opened the topic in the discussions category. I moved it to ā€œOpen Source Projects Ā» Composeā€, now the Solution icon will appear
