• Run the Docker Compose setup: https://github.com/microsoft/vscode-remote-containers/blob/master/CONTRIBUTING.md#docker-compose
• Note that docker ps -a shows the containers having names derived from the project folder name.
• Change the project name and reopen the folder in a container:
  1. By setting the COMPOSE_PROJECT_NAME environment variable and starting Code from the terminal.
  2. By setting the COMPOSE_PROJECT_NAME environment variable in a .env file in the project folder.
• Check with docker ps that the containers are named accordingly.
• Note that the environment variable should win over the value in .env if both are given.

For me, the .env had to be in the parent directory of the docker-compose.yml (so the project directly rather than the .devcontainer directory). Is that expected?

@JacksonKearl Not sure, which OS and docker-compose version are you on?

[JacksonKearl]

docker-compose version 1.24.1, build 4667896b
docker-py version: 3.7.3
CPython version: 3.6.8
OpenSSL version: OpenSSL 1.1.0j  20 Nov 2018

macOS 10.14.6

@JacksonKearl You're right, the .env should be in the project folder (the working directory for the docker-compose command). Thanks for pointing this out.

[rebornix]

It works as described.
