How Can I Configure Ports for a CBH Instance?
To properly use CBH, configure the instance and resource security group ports by referring to Table 1.
- During cross-version upgrade, ports 80, 8080, 443, and 2222 are automatically enabled for the instance. If you do not need to use these ports, disable them immediately after the upgrade.
- During cross-version upgrade, ports 22, 31036, 31679, and 31873 are automatically enabled for the instance. If you do not need to use these ports, disable them immediately after the upgrade.
