Docker Integration

For local builds

Prerequisites

  • Docker v20.10+
  • Docker-compose 2.x.x+
  • Running Ethereum JSON RPC client

Building Docker containers from source

docker-compose up --build
This command uses by-default docker-compose.yml, which builds the explorer into the Docker image and runs 6 Docker containers:
  • Postgres 14.x database, which will be available at port 7432 on localhost.
  • Redis database of latest version, which will be available at port 6379 on localhost.
  • Blockscout explorer at http://localhost:4000.
and 3 Rust microservices:
  • ​Smart-contract-verifier service, which will be available at port 8150 on the host machine.
  • ​Sig-provider service, which will be available at port 8151 on the host machine.
  • ​Sol2UML visualizer service, which will be available at port 8152 on the host machine.

Configs for different Ethereum clients

The repo above contains built-in configs for different clients without needing to build the image.
Note for Linux users: Linux users who run Blockscout in docker with a local node need to run the node on http://0.0.0.0/ rather than http://127.0.0.1/​
  • Erigon: docker-compose -f docker-compose-no-build-erigon.yml up -d
  • Geth: docker-compose -f docker-compose-no-build-geth.yml up -d
  • Nethermind, OpenEthereum: docker-compose -f docker-compose-no-build-nethermind up -d
  • Ganache: docker-compose -f docker-compose-no-build-ganache.yml up -d
  • HardHat network: docker-compose -f docker-compose-no-build-hardhat-network.yml up -d
  • Running only explorer without DB: docker-compose -f docker-compose-no-build-no-db-container.yml up -d. In this case, one container is created - for the explorer itself. And it assumes that the DB credentials are provided through DATABASE_URL environment variable.
All of the configs assume the Ethereum JSON RPC is running at http://localhost:8545.
In order to stop launched containers, run docker-compose -d -f config_file.yml down, replacing config_file.yml with the file name of the config which was previously launched.
You can adjust BlockScout environment variables from ./envs/common-blockscout.env. Descriptions of the ENVs are available in the docs.
