Remote provisioning of hosts in public clouds
Examples provide for automatically provisioning hosts in a cloud environment. A cloud daemon generates a cloud host-state configuration, for a given cloud instance of a host, stored on a cloud metadata service prior to first boot of the given cloud instance of the host. A first boot of a plurality of cloud instances of hosts is performed using a stateless, master boot image lacking host-specific configuration data. On completion of the first boot of a given cloud instance of a host, the cloud host-state configuration is installed on the master boot image to generate a self-configured boot image including host-specific configuration data for the given cloud instance of the host. A second boot is performed on the given cloud instance of the host by executing the self-configured boot image to automatically provision the given cloud instance of the host in the cloud environment.
1. A system for provisioning of cloud instances in a cloud environment, the system comprising:
a memory storing data associated with a plurality of customized configurations associated with cloud instances, and computer-executable instruction; and
at least one processor operationally coupled to the memory and configured to execute the computer-executable instruction to:
create a stateless boot image;
perform a first boot using the stateless boot image to instantiate a cloud instance on at least one server of a cloud environment;
receive customized configuration data associated with the cloud instance;
install the received customized configuration data onto the stateless boot image to generate a second boot image; and
perform a second boot of the cloud instance using the generated second boot image to provision the cloud instance with the customized configuration in the cloud environment.
2. The system of claim 1 , wherein the stateless boot image is immutable.
3. The system of claim 1 , wherein the generated second boot image is a self-configured boot image.
4. The system of claim 1 , further comprising: on determining that the first boot is complete, modifying a first boot script to prevent the first boot script from executing during the second boot.
5. The system of claim 1 , wherein the at least one server is a rule-based deployment server.
6. The system of claim 5 , wherein the rule-based deployment server utilizes a set of rules to create a profile for the customized configuration data in the cloud environment.
7. The system of claim 1 , wherein the processor is configured to further execute the computer-executable instruction to:
read a pointer indicating a location of the customized configuration data associated with the cloud instance; and
obtain the customized configuration data based on the pointer.
8. A method for provisioning of cloud instances in a cloud environment, the method comprising:
creating a stateless boot image;
performing a first boot using the stateless boot image to instantiate a cloud instance on at least one server of a cloud environment;
receiving configuration data associated with the cloud instance, the configuration data defining a customized configuration;
installing the received configuration data onto the stateless boot image to generate a second boot image; and
performing a second boot of the cloud instance using the generated second boot image to provision the cloud instance with the customized configuration in the cloud environment.
9. The method of claim 8 , wherein the stateless boot image is immutable.
10. The method of claim 8 , wherein the generated second boot image is a self-configured boot image.
11. The method of claim 8 , further comprising: on determining that the first boot is complete, modifying a first boot script to prevent the first boot script from executing during the second boot.
12. The method of claim 8 , wherein the cloud environment is a hybrid cloud environment.
13. The method of claim 8 , wherein the at least one server is a rule-based deployment server.
14. The method of claim 13 , wherein the rule-based deployment server utilizes a set of rules to create a profile for the customized configuration data in the cloud environment.
15. One or more non-transitory computer storage media embodying computer executable instructions that when executed by a processor performs operations comprising:
creating a stateless boot image;
performing a first boot using the stateless boot image to instantiate a cloud instance on at least one server of a cloud environment;
receiving configuration data associated with the cloud instance, the configuration data defining a customized configuration;
installing the received configuration data onto the stateless boot image to generate a second boot image; and
performing a second boot of the cloud instance using the generated second boot image to provision the cloud instance with the customized configuration in the cloud environment.
16. The non-transitory computer storage media of claim 15 , wherein the stateless boot image is immutable.
17. The non-transitory computer storage media of claim 15 , wherein the generated second boot image is a self-configured boot image.
18. The non-transitory computer storage media of claim 15 , with further operations comprising: on determining that the first boot is complete, modifying a first boot script to prevent the first boot script from executing during the second boot.
19. The non-transitory computer storage media of claim 15 , wherein the cloud environment is a hybrid cloud environment.
20. The non-transitory computer storage media of claim 15 , wherein the at least one server is a rule-based deployment server.
