You can create a vCloud Director server group by deploying one or more instances of the vCloud Director appliance. You deploy the vCloud Director appliance by using the vSphere Client (HTLM5), the vSphere Web Client (Flex), or VMware OVF Tool.
The vCloud Director appliance is a preconfigured virtual machine that is optimized for running the vCloud Director services.
The appliance is distributed with a name of the form VMware vCloud Director-v.v.v.v-nnnnnn_OVF10.ova, where v.v.v.v represents the product version and nnnnnn the build number. For example: VMware vCloud Director-188.8.131.52-9229800_OVA10.ova.
- VMware Photon™ OS
- The vCloud Director group of services
- PostgreSQL 10
The primary-small and standby-small vCloud Director appliance sizes are suitable for lab or test systems. The primary-large and standby-large sizes meet the minimum sizing requirements for production systems. Depending on the workload, you might need to add additional resources.
Appliance Database Configuration
Starting with version 9.7, the vCloud Director appliance includes an embedded PostgreSQL database with а high availability (HA) function. To create an appliance deployment with a database HA cluster, you must deploy one instance of the vCloud Director appliance as a primary cell, and two instances as standby cells. You can deploy additional instances of the vCloud Director appliance in the server group as vCD application cells, which run only the vCloud Director group of services without the embedded database. vCD application cells connect to the database in the primary cell. See Appliance Deployments and Database High Availability Configuration.
By default, the vCloud Director appliance uses TLS, in place of the deprecated SSL, for database connections, including replication. This feature is active immediately after deployment, using a self-signed PostgreSQL certificate. To use a signed certificate from a certificate authority (CA), see Replace a Self-Signed Embedded PostgreSQL and vCloud Director Appliance Management UI Certificate.
Appliance Network Configuration
eth1, so that you can isolate the HTTP traffic from the database traffic. Different services listen on one or both of the corresponding network interfaces.
The vCloud Director appliance supports user customization of firewall rules by using
iptables. To add custom
iptables rules, you can add your own configuration data to the end of the /etc/systemd/scripts/iptables file.
