Update a Server


ionosctl server update [flags]


For server command:

[s svr]

For update command:

[u up]


Use this command to update a specified Server from a Virtual Data Center.

You can set the RAM size in the following ways:

  • providing only the value, e.g.--ram 256 equals 256MB.

  • providing both the value and the unit, e.g.--ram 1GB.

Note: The amount of memory for the Server must be specified in multiples of 256. The default unit is MB. Minimum: 256MB. Maximum: it depends on your contract limit.

You can wait for the Request to be executed using --wait-for-request option. You can also wait for Server to be in AVAILABLE state using --wait-for-state option. It is recommended to use both options together for this command.

  • Data Center Id
