Below are some useful things for configuring VSCode for development

Setting Up Dev Container

There are two ways you can set up a development container for VSCode.

• Install devcontainers from vscode marketplace
• Attach an existing container (created using docker run for example), do it from the top bar (ctrl+shft+p)
  • see below for building and running a docker image

Manually Building Docker Image

First you need to build a docker image from your Dockerfile. In shell, navigate to where your Dockerfile exists and run the docker build command. Specify the -t flag to name and tag your image (for example, my-image:latest):

docker build -t my-image:latest .

• t assigns a name and tag to the image. The format is name:tag, where tag is optional (default is latest).
• . specifies the build context as the current directory (where your Dockerfile and other resources are located).

Verify the image was created by listing all Docker images:

docker images

Now run a docker container from a specified image:

docker run --name your_container_name -v /path/on/host:/path/in/container my-image:latest

-v specifies volume mounting from host machine to docker container

• /path/on/host: This is the path on your host machine you want to share with the container.
• /path/in/container: This is the path inside the container where the host directory will be mounted.

Now, connect to your remote host as usual. You should see this icon on the left
