@ -76,53 +76,6 @@ You can also build Nu yourself with all the bells and whistles (be sure to have
```shell
cargo build --workspace --features=extra
```
### Docker
#### Quickstart
Want to try Nu right away? Execute the following to get started.
```shell
docker run -it quay.io/nushell/nu:latest
```
#### Guide
If you want to pull a pre-built container, you can browse tags for the [nushell organization](https://quay.io/organization/nushell)
on Quay.io. Pulling a container would come down to:
```shell
docker pull quay.io/nushell/nu
docker pull quay.io/nushell/nu-base
```
Both "nu-base" and "nu" provide the nu binary, however, nu-base also includes the source code at `/code`
in the container and all dependencies.
Optionally, you can also build the containers locally using the [dockerfiles provided](docker):
To build the base image:
```shell
docker build -f docker/Dockerfile.nu-base -t nushell/nu-base .
```
And then to build the smaller container (using a Multistage build):
```shell
docker build -f docker/Dockerfile -t nushell/nu .
```
Either way, you can run either container as follows:
```shell
docker run -it nushell/nu-base
docker run -it nushell/nu
/> exit
```
The second container is a bit smaller if the size is important to you.
