Docker Installation


All the items listed below are required to get the CAD up and running smoothly.

Getting Started

Once you've got all the items installed, we can get started with installing SnailyCADv4. Open the Command Prompt on Windows or the Terminal on Linux.

1. Cloning the GitHub repository


Warning: Do not install SnailyCADv4 in the root folder. Install it in your Documents folder on Windows or home folder on Linux.

To fix this, run the following command:


cd Documents


cd /home/$(whoami)

Firstly, we need to clone the GitHub repository to our local machine:

git clone
Git clone short clip

Once the files have been cloned from GitHub, we can enter that folder:

cd snaily-cadv4
Change directory short clip

2. Configuration

Configuration can be a bit complicated, so pay close attention. The following steps will help you configure SnailyCADv4's environment variables. These variables are used by SnailyCADv4 to connect to the database and store special tokens used for SnailyCAD's features. Tip: In support channels, this will be referenced as the .env file.

We must first copy the .env.example file to .env:


copy .env.example .env


cp .env.example .env
Move env short clip

Now we can start configuring the variables in the .env file. See next step 3.1 .env file.

2.1 .env info

  • POSTGRES_PASSWORD: The password to the PostgreSQL database.
  • POSTGRES_USER: The username to the PostgreSQL database.
  • DB_HOST: The database host.
  • DB_PORT: The port to the database.
  • POSTGRES_DB: The database name.
  • JWT_SECRET: This is a random value to keep the CAD secured.
  • CORS_ORIGIN_URL: The URL/IP to where the CAD is hosted at, e.g., or
  • NEXT_PUBLIC_CLIENT_URL: The URL/IP to where the CAD is hosted at. e.g.: or
  • NEXT_PUBLIC_PROD_ORIGIN: The URL/IP to where the API is hosted at (/v1 is required.). e.g.: or
  • PORT_API: The port where the API should run on. (Default 8080)
  • PORT_CLIENT: The port where the client should run on. (Default: 3000)
  • ENCRYPTION_TOKEN: Used to generate encrypted values. Must be 32 characters long
  • DATABASE_URL: Do not change unless you know what you're doing!

Please take a minute and read the in-depth document for each item here

View Example .env file
# Documentation can be found at:

# This is the password to the postgress database.

# This is the username to the postgress database.

# The database host - Set as 'postgres' when using docker compose

# The database port - keep port as '5432' when using docker compose

# The database name.

# This is a random value to keep the CAD's cookies secured. Make sure to change this!

# string of 32 characters long. Make sure to change this!
# Generate one at:

# This is the URL/IP to your site where the CAD is hosted.
# -> e.g. or

# The URL/IP to where the API is hosted.
# -> e.g. or

# only enter this value if you're using a domain!
# domain should only be the domain, NOT including sub-domains
# example: `DOMAIN=""`

# "true" or "false"
# Can only be enabled when having valid SSL (https) and a domain.

# The port of which the API will run on. Default: 8080
# When using Docker, make sure to change this in the `production.docker-compose.yml` file too.

# The port of which the client will run on. Default: 3000

# Errors get reported to Linear (Project manager). This is done so errors can be fixed faster.

# Do not change this.

# Do not change this, unless you know what you're doing!

2.2 Copying the .env file

After configuring the .env file, we must copy it to the Client and API. This is done by running the following command:

node scripts/copy-env.mjs --client --api

2.3 Docker network

Now we must setup a Docker network so the CAD can communicate with it's services.

docker network create cad_web

3. Building everything

Now we must build the Docker container. This will automatically install the dependencies build the packages and more.


This command must always be run after changing the .env file

docker compose -f production.docker-compose.yml build

4. Starting SnailyCADv4

After completing all the steps above, we are ready to startup the CAD. To do this run the following command:

Note: When running the command for the fist time, this will pull down all services from the Docker Hub. This can take a few minutes.

docker compose -f production.docker-compose.yml up -d
Docker tips
  • Stop SnailyCADv4: enter docker compose -f production.docker-compose.yml down in a command prompt/terminal in the directory where you installed the CAD and wait for the services to stop.

  • View SnailyCADv4 logs: enter docker compose -f production.docker-compose.yml logs in a command prompt/terminal in the directory where you installed the CAD.

5. Accessing SnailyCADv4

Port forwarding

The ports set for the client and API must be forwarded in your firewall if you're not using some proxy.

Default ports:

  • Client port: 3000
  • API port: 8080
  • Proxy ports: 443 and 80

You cannot use localhost to access SnailyCADv4. It will not work!

By default, you can access SnailyCADv4 via a web browser on your LAN IP and the PORT_CLIENT, example: However, if you want to access SnailyCADv4 via a domain, you must setup a reverse proxy. We have guides for NGINX, an Apache Guide can be found here.
