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. After the upgrade, keep prot 31679 enabled and disable other ports immediately if you do not need to use them.
