Starting a Cluster of FTL Servers in Docker Containers

To start FTL servers that require explicit configuration, complete this task.

1. Arrange an FTL server configuration file.
   All the servers in the cluster can use the same configuration file.

   globals:
   
       core.servers:
           ftl1: host1:8585
           ftl2: host2:8585
           ftl3: host3:8585
   
   servers:
   
       ftl1:
           - realm: {}
   
       ftl2:
           - realm: {}
   
       ftl3:
           - realm: {}

   The configuration file can include core servers, auxiliary servers, or both.

2. Load the correct pre-built Docker image.
   The correct image depends on whether a server provides an eFTL service.

   Option	Description
   No eFTL service	ftl-tibftlserver:6.5.0
   eFTL service	ftl-tibeftlserver:6.5.0

   docker load --input ftl-tibftlserver-6.5.0.dockerimage.xz

   docker load --input ftl-tibeftlserver-6.5.0.dockerimage.xz

3. Start the FTL server container.

   To make the configuration file available within the container, bind the external file system with Docker's -v parameter.

   Publish the FTL server port using Docker's -p parameter. This example uses the default port, 8585.

   Supply the configuration file name as the argument to the FTL server's -c parameter.

   Supply the server name as the argument to the FTL server's -n or --name parameter. The name refers to a server defined in the configuration file.

   docker run -v /var/tmp:/tmp
              -p 8585:8585
              ftl-tibftlserver:6.5.0
                    -c /tmp/ftl/ftlconfig.yml
                    -n server_name
   

4. Repeat the preceding step for each FTL server in the configuration file.
   In this example, start three servers:

   • Start server ftl1 on host1.
   • Start server ftl2 on host2.
   • Start server ftl3 on host3.
