Docker

Configuration¶

This image can be run as a service or as a standalone container. Both run Faraday Server without PostgreSQL. You will note that we have created /faraday-storage and /faraday-config volumes (for mounting your storage and configuration). We have also created environment variables for Faraday configuration in case you don't mount a config volume. We will get more in detail of these volumes and environment variables:

Example:

Running Faraday as a standalone container

    docker run \
    ....
    -v /path/to/my_doc_folder:/faraday-license \
    -v /path/to/my_storage_folder:/faraday-storage \
    -v /path/to/my_config_folder:/faraday-config
    ....
  faradaysec/faraday:X.Y.Z

Running Faraday as a service

    vim docker-compose.yml
    version: '4.02'
    services:
      ...
      volumes:
        - /path/to/{my_config_folder}:/home/faraday/.faraday
      ...

We will get more in details about this configuration below.

Environment Variables¶

In case you don't have a configuration file you'll need to set some environment variables. These come with default values so you'll need to customize some or all of them depending on your installation config.

PGSQL_HOST=172.2.0.1 # PostgreSQL server host.
PGSQL_USER=faraday_postgresql # PostgreSQL user
PGSQL_PASSWD=mypgsqlpassword # PostgreSQL user's password.
PGSQL_DBNAME=faraday # Faraday's database name

Running Faraday¶

Now that we have learnt about the volumes and the environment variables above, let's run Faraday assuming we want to connect into PostgreSQL's address 192.168.20.29 and that we have located Faraday's config folder in its default location: ~/.faraday

As a standalone container¶

Run the following command specifying the correct information:

With environment variables

  docker run \
     -v ~/.faraday/doc:/faraday-license \
     -v ~/.faraday/storage:/faraday-storage \
     -p 5985:5985 \
     -e PGSQL_HOST='192.168.20.29' \
     -e PGSQL_PASSWD='mypgsqlpassword' \
     -e LISTEN_ADDR='0.0.0.0' \
     faradaysec/faraday:latest

With config volume mounted

  docker run \
     -v ~/.faraday/doc:/faraday-license \
     -v ~/.faraday/storage:/faraday-storage \
     -v ~/.faraday/config:/faraday-config \
     -p 5985:5985 \
     faradaysec/faraday:latest

To check the container, run the following command:

   docker container ls

As you can see, Faraday Server is running in port 5985.

As a service¶

Initialize a Swarm:

docker swarm init
#  In case you have more than one IP addr configured in your machine you have to specify which one to use.
docker swarm init --advertise-addr=192.168.20.29

Docker Compose File: Now, you need to create a docker-compose.yml file. You can use this docker-compose as example:
With environment variables

version: '4.02' 

services: 
  server: 
    image: faradaysec/faraday:latest
    environment: 
      - LISTEN_ADDR=0.0.0.0 
      - PGSQL_HOST=192.168.20.29 
      - PGSQL_USER=faraday_postgresql 
      - PGSQL_PASSWD=/run/secrets/pgsql_passwd 
      - PGSQL_DBNAME=faraday 
    secrets: 
      - pgsql_passwd 
    ports: 
      - 5985:5985 
    volumes: 
      - ~/.faraday/storage:/faraday-storage 
    deploy: 
      replicas: 1 
      placement: 
        constraints: [node.role == manager] 
secrets: 
  pgsql_passwd: 
    external: true

When Faraday runs as a service, PGSQL_PASSWD can be configured with Docker secrets (default in docker-compose.yml). The simplest way to create a secret is reading from standard input (you should take care of bash history).

printf mypgsqlpassword | docker secret create pgsql_passwd -

Once you have created the secret, edit you docker-compose.yml and set:

vim docker-compose.yml
version: 'latest'
services:
  ...
  environment:
    - PGSQL_PASSWD=/run/secrets/pgsql_passwd  
  ...

For more information about secrets, check Docker’s web page

With config volume mounted

version: '4.02' 

services: 
  server: 
    image: faradaysec/faraday:latest
    ports: 
      - 5985:5985 
    volumes: 
      - ~/.faraday/storage:/faraday-storage 
      - ~/.faraday/config:/faraday-config 
    deploy: 
      replicas: 1 
      placement: 
        constraints: [node.role == manager]

3. Deploy: Once you are done setting up your docker-compile.yml file, lets deploy it by running the following command:

docker stack deploy -c docker-compose.yml faraday

4. Check service: To check the service, run the following command:

 docker service ls
 docker service logs faraday_server

Web UI¶

Once Faraday Server is running, you'll have to obtain the container's IP address. For this, run:

   docker inspect $(docker ps -lq) | grep \"IPAddress

This command will throw the following output:

           "IPAddress": "172.17.0.2",
           "IPAddress": "172.17.0.2",

Now you can direct your browser to http://172.17.0.2:5985/_ui/
