How do I fix this Error 1 when trying to run Site Inspector with Docker?

Have cloned the Site Inspector repo from Github (https://github.com/siteinspector/siteinspector)

Using Microsoft PowerShell:

git clone https://github.com/siteinspector/siteinspector.git

cd siteinspector

docker-compose up

The redis, postgres and app images are loaded into Docker fine, but when I run the container on localHost (808), the container exits with a code: 1.

Exit Code 1 means that a container terminated, typically due to an application error or an invalid reference.

Logs as follows:

I expected Site Inspector to open on the localhost port.

Solution

Please assign a value to the SECRET_KEY_BASE variable in the docker-compose.yml file.

Here is an example:

SECRET_KEY_BASE: 'inputyourkey' # <-- input a key

app example:

#docker-compose.yml
version: '3'

services:
  app:
    depends_on:
      - 'postgres'
      - 'redis'
    image: 'siteinspector/siteinspector:latest'
    ports:
      - '808:808'
    volumes:
      - '.:/app'
    command:  bash -c "rake db:migrate && foreman start"
    environment:
      SECRET_KEY_BASE: 'inputyourkey' # <-- you input a key
      RAILS_LOG_TO_STDOUT: 'true'
      DATABASE_URL: postgresql://postgres:postgres@postgres:5432/siteinspector
      REDIS_URL: redis://redis:6379/0
      PORT: 808
      SIDEKIQ_CONCURRENCY: 10

# ... pass
