Step 2 – Creating a configuration file for self hosted setup

Before installation we need to create a file that will be used for configuring test-at-scale.

  • Open a Terminal of your choice.
  • Move to your desired directory or you can create a new directory and move to it using the following command.

mkdir ~/test-at-scale
cd ~/test-at-scale
  • Download our sample configuration file using the following command.
curl -o .synapse.json
  • This file will be used to store certain parameters such as Lambdatest Secret Key, Git Token, Repository Secrets, Container Registry etc that will be required in configuring test-at-scale on your local/self-hosted environment. You can learn more about the configuration options here.

Step 3 – Installation



Docker Compose

  • Create a configuration file using these steps.
  • Download and run the docker compose file using the following command.

curl -L -o docker-compose.yml
docker-compose up -d

NOTE: This docker-compose file will pull the latest version of synapse.

Without Docker Compose

To get up and running quickly, you can use the following instructions to setup Test at Scale on Self hosted environment without docker-compose.

  • Create a configuration file using these steps.
  • Execute the following command to run Test at Scale docker container

docker network create --internal test-at-scale
docker run β€”name synapse β€”-restart always \
    -v /var/run/docker.sock:/var/run/docker.sock \
    -v /tmp/synapse:/tmp/synapse \
    -v .synapse.json:/home/synapse/.synapse.json \
    -v /etc/machine-id:/etc/machine-id \
    --network=test-at-scale \
