Migrate to the new frontend using Docker

All-In-One Container

{% hint style="info" %} You will use the docker-compose.yml file. {% endhint %}

Prerequisites

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

Please see https://github.com/blockscout/blockscout/tree/master/docker-compose for additional information

Migration

1) Pull changes from the master branch

We assume Blockscout is already deployed in your environment.

git pull origin master

2) Navigate to the docker compose folder

cd docker-compose

3) Adjust backend envs for your instance

Replace the example environment variables in the environment: list of the docker-compose.yml file.

cat docker-compose.yml

By default, standard test setup ENV variables (ganache) are set in the environment: list. Replace these with env vars from your existing backend. The only one you NEED to keep is API_V2_ENABLED='true' . Any values added here will override existing variables when starting the docker container.

environment:
        ETHEREUM_JSONRPC_VARIANT: 'ganache'
        ETHEREUM_JSONRPC_HTTP_URL: http://host.docker.internal:8545/
        ETHEREUM_JSONRPC_WS_URL: ws://host.docker.internal:8545/
        INDEXER_DISABLE_INTERNAL_TRANSACTIONS_FETCHER: 'true'
        INDEXER_DISABLE_PENDING_TRANSACTIONS_FETCHER: 'true'
        DATABASE_URL: postgresql://postgres:@host.docker.internal:7432/blockscout?ssl=false
        ECTO_USE_SSL: 'false'
        SECRET_KEY_BASE: '56NtB48ear7+wMSf0IQuWDAAazhpb31qyc7GiyspBP2vh7t5zlCsF5QDv76chXeN'
        CHAIN_ID: '1337'
        API_V2_ENABLED: 'true'
        MIX_ENV: 'prod'

4) Run docker compose

Run all containers (up) and run processes in the background (-d).

docker-compose up -d

Check progress and view containers:

Docker ps

5) Check the proxy configuration

cd proxy
Cat default.conf.template

Unless you overrode the default configs, you will see the default port for the backend is 4000, and 3000 for the frontend. However, these are not exposed because they are running within the container. This means localhost:3000 will not work.

Since the proxy is in place (listen 80) the whole application should default to port 80 (which is just localhost). So your instance with the new frontend should now be served on localhost. More details about the recommended proxy setup.

{% hint style="info" %} It may take several minutes for the frontend to propagate during this process. {% endhint %}

6) Adjust frontend ENVs if needed

There are several required ENVs for the frontend. If required variables are missing or invalid the frontend will show in error message and will not run the app.

To adjust, stop the frontend container, update the env file (or pass variables directly), and restart the container.

7) Check Microservice ENVs

Typically the default values will provide what you need for the common-visualizer.env, common-stats.env, and common-smart-contract-verifier.env files.

Note that in the smart-contract-verifier.envs the SMART_CONTRACT_VERIFIER__SOLIDITY__FETCHER__LIST__LIST_URL variable is different depending on your OS. The default is Linux, if you are running macOS or Windows be sure to comment out the appropriate variables.
