You can tell the image to clone any repo, passing the GIT_REPO_URL env var, or bind the vscode server to any port using the CODE_SERVER_PORT env var.
docker run -e GIT_REPO_URL=https://github.com/your/repo -e CODE_SERVER_PORT=9090 -p 9090:9090 scarduzio/code-streamlit
Now, open the browser: http://:9090 and start coding in your IDE within a docker container, and run the streamlit app in the same container.
