|
|
|
|
[](https://drone.jacknet.io/jackhadrill/container-spawner)
|
|
|
|
A tool for spawning a bespoke container upon receiving an HTTP request.
|
|
|
|
## Usage
|
|
|
|
More details coming soon.
|
|
|
|
An example `docker-compose.yml` config is show below:
|
|
|
|
```yml
|
|
version: '3'
|
|
services:
|
|
...
|
|
container-spawner:
|
|
image: git.jacknet.io/jackhadrill/container-spawner:latest
|
|
restart: always
|
|
environment:
|
|
CONTAINER_IMAGE: "codercom/code-server:latest"
|
|
CONTAINER_PREFIX: "vscode"
|
|
CONTAINER_NETWORK: "vscode_backend"
|
|
CONTAINER_PERSIST: "/home/coder"
|
|
...
|
|
```
|
|
|
|
## Process description
|
|
|
|
Upon receiving any HTTP request, **Code Spawner** will launch a bespoke container on behalf of the user (if not already existing), equivalent to having used the command below. The user's name is derived from the `X-Forwarded-Preferred-User` header, original sent by [**OAuth2 Proxy**](https://github.com/oauth2-proxy/oauth2-proxy).
|
|
|
|
```bash
|
|
$ docker run -d --rm --name ${CONTAINER_PREFIX}-${X-Forwarded-Preferred-User} -v ${CONTAINER_PREFIX}-${X-Forwarded-Preferred-User}:${CONTAINER_PERSIST} --network ${CONTAINER_NETWORK} ${IMAGE_NAME}
|
|
```
|
|
|
|
For example, assuming `X-Forwarded-Preferred-User` is `jack`:
|
|
|
|
```bash
|
|
$ export CONTAINER_IMAGE="codercom/code-server:latest"
|
|
$ export CONTAINER_PREFIX="vscode"
|
|
$ export CONTAINER_NETWORK="vscode_backend"
|
|
$ export CONTAINER_PERSIST="/home/coder"
|
|
$ docker run -d --rm --name vscode-jack -v vscode-jack:/home/coder --network vscode_backend codercom/code-server:latest
|
|
```
