Remote Containers Smoke Test

Instructions on how to smoke-test the Remote Containers extension before a release.

Single container

• Open an empty folder.
• Create a Dockerfile:

FROM node:lts

• Run the Reopen Folder in Container command.
• Pick From 'Dockerfile'.
• Wait for container to start and Code to connect to it.
• Create a server.js:

require('http')
    .createServer((req, res) => {
        res.end('Hello!');
    })
    .listen(0);

• Check IntelliSense and hovers work.
• Place a breakpoint and F5.
• Run the Forward Port from Container... command to forward the port and open the browser on it.
• Check breakpoint is hit.
• Add RUN touch /foobar to the end of the Dockerfile.
• Reload window, check it reconnects to the container and /foobar does not exist.
• Run the Rebuild Container command, check it reconnects to a container and /foobar does exist.

Docker Compose

• Open an empty folder.
• Run the Reopen Folder in Container command.
• Pick Node.js & Mongo DB.
• Wait for containers to start and Code to connect to one.
• Verify the ESLint extension is installed.
• Add RUN touch /foobar to the end of the Dockerfile.
• Reload window, check it reconnects to the container and /foobar does not exist.
• Run the Rebuild Container command, check it reconnects to a container and /foobar does exist.

Attach to Container

• Open empty local window.
• Install Docker extension.
• Run docker run -d debian sleep infinity form the terminal.
• In the Docker viewlet right-click the debian container and run Attach Visual Studio Code.
• In the new window open some folder in the container and check the window reconnects to the container with that folder open.
