• installing and persisting packages
• updating to newer versions
• etc.

From older Kapitan Hull guide site:

Customising VSCode Server

The prebuilt VSCode image was built using a Dockerfile which can be
found in this repository at
docker/vscode-server/vscode-server.Dockerfile.
The Dockerfile was customised by the MLOps team at AI Singapore to
include tools deemed relevant for machine learning development, in the
context of the organisation's tech stack and infrastructure.

Aside from the server itself, here are some of the tools that are
included in the image:

• Git
• Miniconda
• kubectl
• Helm
• AWS CLI

Often times, project teams would like to further customise the VSCode
server image to their liking. One can edit the Dockerfile and build the
custom image:

=== "Linux/macOS"

```bash
docker build \
    -t {{cookiecutter.registry_project_path}}/vscode-server-custom:0.1.0 \
    -f docker/vscode-server/vscode-server.Dockerfile \
    --platform linux/amd64 .
docker push {{cookiecutter.registry_project_path}}/vscode-server-custom:0.1.0
```

=== "Windows PowerShell"

```powershell
docker build `
    -t {{cookiecutter.registry_project_path}}/vscode-server-custom:0.1.0 `
    -f docker/vscode-server/vscode-server.Dockerfile `
    --platform linux/amd64 .
docker push {{cookiecutter.registry_project_path}}/vscode-server-custom:0.1.0
```
