Docker

A Docker container allows you to easily run a node without depending on the platform it is running on. This method should only be used if you already have experience with Docker containers.

Installation​

Start by installing docker: How to install Docker on Ubuntu

Create a local directory for the chain storage data and a dedicated user:

sudo mkdir /var/lib/astar
sudo useradd --no-create-home --shell /usr/sbin/nologin astar
sudo chown astar:astar /var/lib/astar

Start Docker node​

This guide goes over the process of starting a container with both WS and RPC endpoints. For a single type of endpoint, simply remove the unnecessary port and command.

Launch the docker node in detached mode:

tip

Make sure to change the {NODE_NAME}

docker run -d \
--name astar-container \
-u $(id -u astar):$(id -g astar) \
-p 30333:30333 \
-p 9944:9944 \
-v "/var/lib/astar/:/data" \
staketechnologies/astar-collator:latest \
astar-collator \
--pruning archive \
--rpc-cors all \
--name {NODE_NAME} \
--chain astar \
--base-path /data \
--rpc-external \
--rpc-methods Safe \
--rpc-max-request-size 1 \
--rpc-max-response-size 1 \
--telemetry-url 'wss://telemetry.polkadot.io/submit/ 0'

Test the node health via the RPC port with this command:

curl -H "Content-Type: application/json" --data '{ "jsonrpc":"2.0", "method":"system_health", "params":[],"id":1 }' localhost:9944

Next steps​

In any case, wait for the chain to be fully synchronized by checking the node log.

How the archive node will be used will largely determine what steps to follow next:

  • If accessing the node publicly, running an nginx server is the recommended option.
  • If the dApp is running on the same server as the node, then it can be accessed directly with the localhost address. This setup is recommended for testing purposes only.
  • If running the node locally for testing purposes, switch networks in Polkadot.js portal to explore the chain:

Extra Operations​

Get node logs​

To obtain the last 100 lines from the node logs, use the following command:

docker logs -f -n 100 $(docker ps -aq --filter name="{CHAIN}-container")

replacing {CHAIN} with astar, shiden, or shibuya

eg.

docker logs -f -n 100 $(docker ps -aq --filter name="astar-container")

Indexers and Oracles​

To access data from indexers (like The Graph) or Oracles (like Chainlink), add the follwing debug flags to the node launch command, after the astar-collator line:

--ethapi=debug

Upgrade node​

When a node upgrade is necessary, node operators are notified with instructions in the Astar Dev Announcement Telegram, Astar Discord, and Astar Node Upgrade Element channel. Join and follow any of these channels to receive news about node updates and node upgrades.

To upgrade to the latest node version, stop and remove the actual container:

docker stop $(docker ps -q --filter name="{CHAIN}-container")
docker rm $(docker ps -a -q --filter name="{CHAIN}-container")

where {CHAIN} is astar, shiden, or shibuya.

Then start a new container with the information under "Start Docker Node". Chain data will be kept on your machine under /var/lib/astar/.

Purge node​

To start a new container from scratch without any chain data, simply remove the container and wipe the chain data directory:

docker rm -f $(docker ps -a -q --filter name="CHAIN-container")
sudo rm -R /var/lib/astar/*

where CHAIN is astar, shiden, or shibuya.

Then start a new container by following the instructions under the Start Docker node section.
