# Using Containers
|
|
|
|
Using containers via **Podman** or **Docker** brings benefit, whether it is to build a container image or run a node
|
|
while keeping a minimum footprint on your local system.
|
|
|
|
This document mentions using `podman` or `docker`. Those are usually interchangeable and it is encouraged using
|
|
preferably **Podman**. If you have podman installed and want to use all the commands mentioned below, you can simply
|
|
create an alias with `alias docker=podman`.
|
|
|
|
There are a few options to build a node within a container and inject a binary inside an image.
|
|
|
|
## Parity built container image
|
|
|
|
Parity builds and publishes a container image that can be found as `docker.io/parity/polkadot-parachain`.
|
|
|
|
## Parity CI image
|
|
|
|
Parity maintains and uses internally a generic "CI" image that can be used as a base to build binaries: [Parity CI
|
|
container image](https://github.com/paritytech/scripts/tree/master/dockerfiles/ci-unified):
|
|
|
|
The command below allows building a Linux binary without having to even install Rust or any dependency locally:
|
|
|
|
```bash
|
|
docker run --rm -it \
|
|
-w /polkadot-sdk \
|
|
-v $(pwd):/polkadot-sdk \
|
|
paritytech/ci-unified:bullseye-1.75.0-2024-01-22-v20240222 \
|
|
cargo build --release --locked -p polkadot-parachain-bin --bin polkadot-parachain
|
|
sudo chown -R $(id -u):$(id -g) target/
|
|
```
|
|
|
|
## Injected image
|
|
|
|
Injecting a binary inside a base image is the quickest option to get a working container image. This only works if you
|
|
were able to build a Linux binary, either locally, or using a container as described above.
|
|
|
|
After building a Linux binary (`polkadot-parachain`) with cargo or with Parity CI image as documented above, the
|
|
following command allows producing a new container image where the compiled binary is injected:
|
|
|
|
```bash
|
|
ARTIFACTS_FOLDER=./target/release /docker/scripts/build-injected.sh
|
|
```
|
|
|
|
## Container build
|
|
|
|
Alternatively, you can build an image with a builder pattern. This options takes a while but offers a simple method for
|
|
anyone to get a working container image without requiring any of the Rust toolchain installed locally.
|
|
|
|
```bash
|
|
docker build \
|
|
--tag $OWNER/$IMAGE_NAME \
|
|
--file ./docker/dockerfiles/polkadot-parachain/polkadot-parachain_builder.Dockerfile .
|
|
```
|
|
|
|
You may then run your new container:
|
|
|
|
```bash
|
|
docker run --rm -it \
|
|
$OWNER/$IMAGE_NAME \
|
|
--collator --tmp \
|
|
--execution wasm \
|
|
--chain /specs/asset-hub-westend.json
|
|
```
