红帽全球峰会4.6. Enabled services on custom images
When you use RHEL image builder to configure a custom image, the default services that the image uses are determined by specifications, such as the RHEL version release on which you use the image-builder utility, and the image type.
For example, the ami image type enables the sshd, chronyd, and cloud-init services by default. If these services are not enabled, the custom image does not boot.
| Image type | Default enabled Services |
|---|---|
|
| sshd, cloud-init, cloud-init-local, cloud-config, cloud-final |
|
| sshd, cloud-init, cloud-init-local, cloud-config, cloud-final |
|
| cloud-init |
|
| No extra service is enabled by default |
|
| sshd, chronyd, waagent, cloud-init, cloud-init-local, cloud-config, cloud-final |
|
| sshd, chronyd, vmtoolsd, cloud-init |
You can customize which services to enable during the system boot. However, the customization does not override services enabled by default for the mentioned image types.
