Arbitrator cluster settings

Set up a senhasegura cluster

You should have the following environment to be able to perform the actions below:

• senhasegura primary instance: 192.168.0.8
• senhasegura secondary instance: 192.168.0.9
• Linux machine with Docker host: 192.168.0.5

1. Define the cluster with Arbitrator:

   Info

   If you don't have a configured and functional cluster, the command below will also set up the cluster. Therefore, it's not necessary to configure the cluster beforehand.

   1. Enter the following command on the primary instance of the cluster:

          orbit cluster config --nodes=192.168.0.8,192.168.0.9 --ip=192.168.0.8 --arbiter=192.168.0.5 --segment=0 --latency="high"
      

   2. Start the cluster with the following command on the primary instance:

      orbit cluster start
      

   3. Enter the following command on the secondary instance of the cluster:

      orbit cluster config --nodes=192.168.0.8,192.168.0.9 --ip=192.168.0.9 --arbiter=192.168.0.5 --segment=0 --latency="high"
      

   4. Start the cluster with the following command on the secondary instance:

      orbit cluster start
      

2. Set up Elasticsearch

   Info

   This process can take several minutes.

   • Enter the following command on the primary instance of the cluster:

     orbit elasticsearch setup
     

   • Enter the following command on the secondary instance of the cluster:

     orbit elasticsearch setup
     

3. Restart the senhasegura cluster

   Warning

   During the execution of this process, the senhasegura database will be restarted so that the environment may experience a brief unavailability

   • Enter the following command on the primary instance of the cluster:

     orbit cluster stop
     orbit cluster start
     

   • Enter the following command on the secondary instance of the cluster:

     orbit cluster stop
     orbit cluster start
     

Transfer files to Docker host

Log in via SSH (59022) on the primary senhasegura instance and follow these steps:

1. Generate the Arbiter config file and the Docker image

orbit cluster arbiter create-config

After this process, two files will be created in the path: /var/tmp/senhasegura-cluster-arbiter/

• manifests.tar.gz: contains the files needed to run the arbitrator containers. It helps if you transfer it to the remote machine that will be running Arbitrator. For more detailed instructions, access the README file.

• docker-images.tar.gz: contains the container images themselves. Transferring this file is optional. You can download the image directly from the docker registry, as explained in the file.

2. Transfer the manifests.tar.gz file to the Docker host via scp

• Docker host with internet access

Docker host needs to have access to registry.senhasegura.io.

Transfer the manifests.tar.gz file to the machine with docker and docker-compose:

scp /var/tmp/senhasegura-cluster-arbiter/manifests.tar.gz [email protected]:/tmp/

Docker host without internet access

To an offline environment, you need to transfer the manifests and docker-images files to Docker host.

• Transfer manifests.tar.gz

scp /var/tmp/senhasegura-cluster-arbiter/manifests.tar.gz [email protected]:/tmp/

• Transfer docker-images.tar.gz

scp /var/tmp/senhasegura-cluster-arbiter/docker-images.tar.gz [email protected]:/tmp/

Next steps

• Set up Docker host
