blockscout/docker

BlockScout Docker integration

For now this integration is not production ready. It made only for local usage only !

How to use ?

First of all blockscout requires PostgreSQL server for working. It will be provided by starting script (new docker image will be created named postgres)

Starting command make start - will set everything up and start blockscout in container. To connect it to your local environment you will have to configure it using env variables

Exmaple connecting to local ganache instance running on port 2000 on Mac/Windows:

COIN=DAI \
ETHEREUM_JSONRPC_VARIANT=ganache \ 
ETHEREUM_JSONRPC_HTTP_URL=http://host.docker.internal:2000 \
ETHEREUM_JSONRPC_WEB_SOCKET_URL=ws://host.docker.internal:2000 \
make start

Blockscout will be available on localhost:4000

Note On mac/Windows Docker provides with a special URL host.docker.internal that will be available into container and routed to your local machine. On Linux docker is starting using --network=host and all services should be available on localhost

Migrations

By default Makefile will do migrations for you on PostgreSQL creation. But you could run migrations manualy using make migrate command.

WARNING Migrations will clean up your local database !

Env variables

BlockScout support 3 different JSON RPC Variants. Vriant could be configured using ETHEREUM_JSONRPC_VARIANT environment variable.

Example:

ETHEREUM_JSONRPC_VARIANT=ganache make start

Available options are:

• parity - Parity JSON RPC (Default one)
• geth - Geth JSON RPC
• ganache - Ganache JSON RPC

Variable	Description	Default value
ETHEREUM_JSONRPC_VARIANT	Variant of your JSON RPC service: parity, geth or ganache	parity
ETHEREUM_JSONRPC_HTTP_URL	HTTP JSON RPC URL Only for geth or ganache variant	Different per JSONRPC variant
ETHEREUM_JSONRPC_WS_URL	WS JSON RPC url	Different per JSONRPC variant
ETHEREUM_JSONRPC_TRACE_URL	Trace URL Only for parity variant	https://sokol-trace.poa.network
COIN	Default Coin	POA
