Docker

Requirements

Install Docker on your machine;
Make sure Docker Compose is installed and available (it should be the case if you have chosen to install Docker via Docker Desktop); and
Make sure Git is installed on your machine.

Run the app

To start using Lago, run the following commands in a shell:

# Get the code
git clone https://github.com/getlago/lago.git

# Go to Lago folder
cd lago

# Set up environment configuration
echo "LAGO_RSA_PRIVATE_KEY=\"`openssl genrsa 2048 | base64`\"" >> .env
source .env

# Start
docker-compose up

You can now open your browser and go to http://localhost to connect to the application. Just after signing up, Lago’s API is exposed at http://localhost:3000.

Signing up

It’s mandatory to create your organization by signing up to Lago. This organization is the core object of your biller as it’s used to invoice your customers.

Write down your organization name;
Use the main billing email of your company; and
Define the admin password for this email.

You will be able to invite other email addresses within the application. If you already have an account, you can also log in. Once you are able to access the app, you can retrieve your API key.

Find your API Key

Your API Key can be found directly in the UI:

Access the Developer section from the sidebar;
The first tab of this section is related to your API keys; and
Click the Copy button to copy it to clipboard.

Configuration

Version

Docker images are always updated to the last stable version in the docker-compose.yml file. You can use a different tag if needed by checking the releases list.

We recommend to avoid the usage of latest tag, you should use the last tagged version, you can track what are the last version on Dockerhub

lago-api : https://hub.docker.com/repository/docker/getlago/api
lago-front : https://hub.docker.com/repository/docker/getlago/front

SECRET_KEY_BASE can be generated using the openssl rand -hex 64 command.
LAGO_RSA_PRIVATE_KEY can be generated using the openssl genrsa 2048 | base64 command.
LAGO_ENCRYPTION_PRIMARY_KEY, LAGO_ENCRYPTION_DETERMINISTIC_KEY and LAGO_ENCRYPTION_KEY_DERIVATION_SALT can all be gerated using the cat /dev/urandom | tr -dc 'a-zA-Z0-9' | fold -w 32 | head -n 1 command.

Components

Lago uses the following containers:

Container	Role
`front`	Front-end application
`api`	API back-end application
`api_worker`	Asynchronous worker for the API application
`api_clock`	Clock worker for the API application
`db`	Postgres database engine used to store application data
`redis`	Redis database engine used as a queuing system for asynchronous tasks
`pdf`	PDF generation powered by Gotenberg

You can also use your own database or Redis server. To do so, remove the db and redis configurations from the docker-compose.yml file and update the environment variables accordingly.

SSL Support

Lago Front application can be configured to support SSL certificates. You have two options to achieve this:

by using a self-signed certificate
by using a signed certificate generated by Let’s Encrypt

Self Signed Certificate

Run the script to generate the certificates

# Be sure to be in your lago folder
./extra/init-selfsigned.sh

# This should create certificates in the ./extra/ssl/ folder

Take a look at the docker-compose.yml file and uncomment the part related to the Self-Signed certificate

volumes:
  - ./extra/nginx-selfsigned.conf:/etc/nginx/conf.d/default.conf
  - ./extra/ssl/nginx-selfsigned.crt:/etc/ssl/certs/nginx-selfsigned.crt
  - ./extra/ssl/nginx-selfsigned.key:/etc/ssl/private/nginx-selfsigned.key
  - ./extra/ssl/dhparam.pem:/etc/ssl/certs/dhparam.pem

You can now start the front application with a self signed SSL certificate support

docker-compose up front

Let’s Encrypt Certificate

Edit the file extra/init-letsencrypt.sh
- You must replace lago.example with your domain name
- You must enter a valid email address
Edit the file extra/nginx-letsencrypt.conf
- You must replace lago.example with your domain name
Run the script

# Be sure to be in your lago folder
./extra/init-letsencrypt.sh

# You will be asked to provide some information
# After that you should be able to see the extra/certbot folder

Take a look at the docker-compose.yml file and uncomment all the parts related to the Let’s Encrypt’s support

command:
  '/bin/sh -c ''while :; do sleep 6h & wait $${!}; nginx -s reload; done & nginx
  -g "daemon off;"'''
---
volumes:
  - ./extra/nginx-letsencrypt.conf:/etc/nginx/conf.d/default.conf
  - ./extra/certbot/conf:/etc/letsencrypt
  - ./extra/certbot/www:/var/www/certbot

You can now start the front application with the signed certificate support

docker-compose up front

Storage

By default, Lago uses the internal storage of the container. You can customize it by defining different environment variables. We currently support :

AWS S3
AWS S3 Compatibles Endpoints
Google Cloud Service Cloud Storage

If you use S3 compatibles endpoints, you should set the LAGO_AWS_S3_REGION to a default value (ei: us-east-1), it is required to work properly!

AWS S3

You have to set these variables to use AWS S3.

Name	Description
`LAGO_USE_AWS_S3`	Set to “true” if you want to use AWS S3
`LAGO_AWS_S3_ACCESS_KEY_ID`	AWS S3 Credentials Access Key Id
`LAGO_AWS_S3_SECRET_ACCESS_KEY`	AWS S3 Credentials Secret Access Key
`LAGO_AWS_S3_REGION`	AWS S3 Region
`LAGO_AWS_S3_BUCKET`	AWS S3 Bucket

AWS S3 Compatible Endpoints

You have to set these variables to use AWS S3 Compatible Endpoints.

Name	Description
`LAGO_USE_AWS_S3`	Set to “true” if you want to use AWS S3 Compatible Endpoints
`LAGO_AWS_S3_ENDPOINT`	AWS S3 Compatible Endpoint
`LAGO_AWS_S3_ACCESS_KEY_ID`	AWS S3 Credentials Access Key Id
`LAGO_AWS_S3_SECRET_ACCESS_KEY`	AWS S3 Credentials Secret Access Key
`LAGO_AWS_S3_BUCKET`	AWS S3 Bucket
`LAGO_AWS_S3_REGION`	Not used but required by the AWS SDK

Google Cloud Service Cloud Storage

You have to set those variables to use GCS Cloud Storage.

Name	Description
`LAGO_USE_GCS`	Set to “true” if you want to use GCS Cloud Storage
`LAGO_GCS_PROJECT`	GCS Project name
`LAGO_GCS_BUCKET`	GCS Bucket name

In the docker-compose.yml file, you must uncomment the lines and pass the correct GCS credentials json file.

api:
  volumes:
    - gcs_keyfile.json:/app/gcs_keyfile.json

api-worker:
  volumes:
    - gcs_keyfile.json:/app/gcs_keyfile.json

SMTP Configuration

In order to use the email feature, you need to configure some environment variables.
