Deploying Chatwoot Rails, Chatwoot Sidekiq as separate services

[shubhenducw]

Hello World and Team Chatwoot,

Is it possible to deploy Rails and Sidekiq as separate services via two dockerfiles and using postgres and redis via add on services provided by cloud provider?

[H-Hp]

Yes, it is possible to deploy Rails and Sidekiq as separate services using two different Dockerfiles, and leverage PostgreSQL and Redis as add-on services provided by a cloud provider.

Here's a general overview of the steps you can follow:

1. Create a Dockerfile for the Rails application:

   • Set up the base image (e.g., ruby:3.0.0)
   • Install system dependencies
   • Copy the Rails application code
   • Install Ruby gems
   • Set the environment variables
   • Expose the necessary port (e.g., 3000)
   • Define the command to start the Rails server

2. Create a Dockerfile for the Sidekiq service:

   • Set up the base image (e.g., ruby:3.0.0)
   • Install system dependencies
   • Copy the Rails application code
   • Install Ruby gems
   • Set the environment variables
   • Define the command to start the Sidekiq process

3. Create a Docker Compose file (docker-compose.yml):

   • Define the services (Rails and Sidekiq)
   • Map the necessary volumes for code and data persistence
   • Set environment variables for each service
   • Define the dependencies between services (e.g., Rails depends on PostgreSQL and Redis)
   • Configure the networking between services

4. Set up PostgreSQL and Redis as add-on services:

   • Most cloud providers offer managed PostgreSQL and Redis services
   • Provision these services and obtain the connection details (hostname, port, credentials)
   • Update your Rails application's configuration files with the connection details

5. Build and run the Docker containers:

   • Use docker-compose build to build the Docker images
   • Use docker-compose up to start the containers
   • The Rails application and Sidekiq service will run in separate containers, connected to the managed PostgreSQL and Redis services

By separating the Rails application and Sidekiq into separate services, you can scale them independently and manage their resources more efficiently. Additionally, using managed PostgreSQL and Redis services from your cloud provider can offload the responsibility of managing and scaling these data stores, allowing you to focus on your application's core functionality.

Note that you might need to configure networking and security rules in your cloud provider to allow communication between your Docker containers and the managed services. Also, make sure to follow best practices for securing your Docker containers and managing secrets (e.g., using environment variables or Docker Secrets).

Hi,

Do you have more detailed (Dockerfile) examples for Rails and Sidekiq ?

Thanks!

[shubhenducw]

Thank you for the response,

I have set two different dockerfile as below, now the problem is how to connect to managed PostgreSQL and Redis services to both app via .env

referred from steps to build image yourself https://www.chatwoot.com/docs/self-hosted/deployment/docker/

for rails app

FROM chatwoot/chatwoot:latest

RUN chmod +x docker/entrypoints/rails.sh

EXPOSE 3000
CMD ["rails", "server", "-b", "0.0.0.0", "-p", "3000"]

for sidekiq App

# Extend from the Chatwoot base image
FROM chatwoot/chatwoot:latest

# Set the working directory
WORKDIR /app

# Command to start Sidekiq
CMD ["bundle", "exec", "sidekiq", "-C", "config/sidekiq.yml"]

Hi, I think I got it,

Here's what I did

Docker File for Sidekiq

# Extend from the Chatwoot base image
FROM chatwoot/chatwoot:latest

# Set the working directory
WORKDIR /app

ENV RAILS_ENV=production \
    REDIS_URL=${REDIS_URL}

RUN chmod +x docker/entrypoints/rails.sh
ENTRYPOINT ["docker/entrypoints/rails.sh"]


# Command to start Sidekiq
CMD ["bundle", "exec", "sidekiq", "-C", "config/sidekiq.yml"]

Dockerfile for Rails App

FROM chatwoot/chatwoot:latest

RUN chmod +x docker/entrypoints/rails.sh

ENTRYPOINT ["docker/entrypoints/rails.sh"]

EXPOSE 3000

CMD ["bundle", "exec", "rails", "s", "-b", "0.0.0.0", "-p", "3000"]

env for rails app, for more details please refer https://www.chatwoot.com/docs/self-hosted/configuration/environment-variables

DATABASE_URL=your db url

POSTGRES_HOST=your host
POSTGRES_PORT="5432"
POSTGRES_DATABASE=your db name
POSTGRES_USER=your db user
POSTGRES_PASSWORD=your db password

REDIS_URL=your redis url
REDIS_PASSWORD=your redis password

ACTIVE_STORAGE_SERVICE="local"
LOG_LEVEL="error"
LOG_SIZE="1024"
ENABLE_ACCOUNT_SIGNUP=true
DIRECT_UPLOADS_ENABLED=false
DEFAULT_LOCALE="en"

And add these 3 as build time variables as well for both services (rails app and sidekiq worker as well)

NODE_ENV="production"
RAILS_ENV="production"
INSTALLATION_ENV="docker"

Thank you 🎉, happy coding all 💻

@shubhenducw looks good but did you need to use the chatwoot image for rails and sidekiq I would like to use something more native.

Did you try that ?
