Docker-compose configuration

Runs Blockscout locally in Docker containers with docker-compose.

Prerequisites

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

Building Docker containers from source

Note: in all below examples, you can use docker compose instead of docker-compose, if compose v2 plugin is installed in Docker.

cd ./docker-compose
docker-compose up --build

Note: if you don't need to make backend customizations, you can run docker-compose up in order to launch from pre-build backend Docker image. This will be much faster.

This command uses docker-compose.yml by-default, which builds the backend of the explorer into the Docker image and runs 9 Docker containers:

• Postgres 14.x database, which will be available at port 7432 on the host machine.
• Redis database of the latest version.
• Blockscout backend with api at /api path.
• Nginx proxy to bind backend, frontend and microservices.
• Blockscout explorer at http://localhost.

and 5 containers for microservices (written in Rust):

• Stats service with a separate Postgres 14 DB.
• Sol2UML visualizer service.
• Sig-provider service.
• User-ops-indexer service.

Note for Linux users: Linux users need to run the local node on http://0.0.0.0/ rather than http://127.0.0.1/

Configs for different Ethereum clients

The repo contains built-in configs for different JSON RPC clients without need to build the image.

JSON RPC Client	Docker compose launch command
Erigon	docker-compose -f erigon.yml up -d
Geth (suitable for Reth as well)	docker-compose -f geth.yml up -d
Geth Clique	docker-compose -f geth-clique-consensus.yml up -d
Nethermind, OpenEthereum	docker-compose -f nethermind up -d
Ganache	docker-compose -f ganache.yml up -d
HardHat network	docker-compose -f hardhat-network.yml up -d

• Running only explorer without DB: docker-compose -f external-db.yml up -d. In this case, no db container is created. And it assumes that the DB credentials are provided through DATABASE_URL environment variable on the backend container.
• Running explorer with external backend: docker-compose -f external-backend.yml up -d
• Running explorer with external frontend: docker-compose -f external-frontend.yml up -d
• Running all microservices: docker-compose -f microservices.yml up -d

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:

• for backend in ./envs/common-blockscout.env
• for frontend in ./envs/common-frontend.env
• for stats service in ./envs/common-stats.env
• for visualizer in ./envs/common-visualizer.env
• for user-ops-indexer in ./envs/common-user-ops-indexer.env

Descriptions of the ENVs are available

• for backend
• for frontend.

Running Docker containers via Makefile

Prerequisites are the same, as for docker-compose setup.

Start all containers:

cd ./docker
make start

Stop all containers:

cd ./docker
make stop

Note: Makefile uses the same .env files since it is running docker-compose services inside.
