Looking at the documentation, when accessing TryMe from outside a VM running a Solace software event broker in Docker, there are a few key networking considerations:

  1. When running in Docker, localhost or 127.0.0.1 from inside the container refers to the container itself, not the host machine
  2. The TryMe interface uses WebSocket protocol (ws://) to connect to the event broker
  3. Proper port mapping is required between the Docker container and the host VM

To resolve connectivity issues:

  1. Create a Docker network to enable communication between containers:
docker network create solace-net
  1. Connect your event broker container to the network:
docker network connect solace-net <container-name>

  1. Ensure proper port mapping when starting the container, particularly port 8008 for WebSocket connections

  2. When accessing TryMe from outside the VM, use the VM’s IP address instead of localhost
