# Building Blog OS using Docker
|
||||
Inspired by [redox].
|
||||
You just need `git`, `make`, and `docker`.
|
||||
It is beter to use a non-privileged user to run the `docker` command, which is usually achieved by adding the user to the `docker` group.
|
||||
|
||||
## Run the container to build Blog OS
|
||||
You can build the docker image using `make docker_build` and run it using `make docker_run`.
|
||||
|
||||
## Run the container interactively
|
||||
You can use the `make` target `docker_interactive` to get a shell in the container.
|
||||
|
||||
## Clear the toolchain caches (Cargo & Rustup)
|
||||
To clean the docker volumes used by the toolchain, you just need to run `make docker_clean`.
