Perform the following upgrade process for containers running on BlueCat DNS/DHCP Server appliances that are unable to access Gateway image repositories.
To upgrade a custom container via Gateway image upload:
-
Stop the Gateway container:
- Select the Servers tab in the sidebar, then select Servers.
- Select the name of a server.
- Select the Services tab.
- Under Core services, locate the Gateway service panel.
- Select Actions > Stop.
-
Disable the Gateway service and remove the image.
- From the Gateway service panel, select Edit service.
- Select the Delete image on disable checkbox.
-
(Optional) Select the Delete mount point on
disable checkbox only if you wish to remove all
unused local volumes and the configured data and logs bind mounts. Leave
the Delete mount point on disable unselected if
you would like the data and logs bind mounts to persist on the DNS/DHCP
Server during the upgrade.
Attention: If you select Delete mount point on disable the mounted data and logs directories will be deleted from the DNS/DHCP Server permanently. This is an irrevocable step.
- Deselect the Enabled checkbox.
- Select Save. Gateway Service removes the image from the BDDS appliance and stops.
-
Re-enable the Gateway service with the new repository image.
- From the Gateway service panel, select Edit service.
-
Under General, set the following parameters:
- Enabled—select this check box to enable BlueCat Gateway service.
- Select Upload image file. The
following field appears:
- Upload image file—drag and drop or select the Gateway image file to upload.
Tip: The format of the Gateway image file must be either tar or tar.gz.Attention: There is no file size limit when uploading Gateway images through the UI, but users are advised to check that Address Manager and DNS/DHCP Servers have sufficient resources and partition sizes to handle larger images, to avoid timeouts and errors.
-
On the Port mapping tab, set the following parameters:
- Host port and Container port—enter a list of ports to configure for BlueCat Gateway. Select the Add (+) button to add a port.
-
On the Environment variables tab, set the following
parameters:
- Name and
Value—enter a list of environment
variables to pull to a container during startup. Select the
Add (+) button to add a
variable.Note: Enter only the required environment variable(s) in this field. Do not include the
-eflag. For example,SESSION_COOKIE_SECURE=False.
- Name and
Value—enter a list of environment
variables to pull to a container during startup. Select the
Add (+) button to add a
variable.
-
On the Volume mounts tab, set the following parameters:
- Source and Container
path——set the directories that will be bind
mounted to the container for data and logging.Note: If you left the mounted data and logs directories on the DNS/DHCP Server when disabling the service, ensure that the directories match the previous bind mounts so the new service can access the existing data.If you deleted the bind mounts when disabling the service, note the following for configuring new directories: to ensure data persistence when patching or upgrading DNS/DHCP servers, BlueCat recommends using the default directory configuration or designated custom directory location. The recommended default configuration is
/root/gwdata/:/bluecat_gateway/and/var/log/gateway/:/logs/. To set custom directories, click Remove to remove the existing directories, then add the custom data and logs directories.Attention: When configuring custom data and logs directories:- Specify only two directories, one for data and one for logs.
- Use the format
[SOURCE:]TARGET.- The
SOURCEis the DNS/DHCP Server directory that will be bind mounted to the container. Custom source directories must be located in/root/gwmount/(i.e. /root/gwmount/customdir/) to ensure data persistence when patching or upgrading DNS/DHCP servers. For a basic configuration of the Gateway on BDDS service, theTARGETportion determines if the directory is for data and logs, and should be either/bluecat_gateway/for data, or/logs/for logs. - Example:
/root/gwmount/mydata1/:/bluecat_gateway/ - Example:
/root/gwmount/customlogsdir/:/logs/
- The
Warning: Ensure that the service is configured as detailed above using either the default directories (/root/gwdata/:/bluecat_gateway/and/var/log/gateway/:/logs/) or designated custom directory location (/root/gwmount/). Data located outside of these directories will be lost upon patch or upgrade of the DNS/DHCP Server.
- Source and Container
path——set the directories that will be bind
mounted to the container for data and logging.
-
Select Save.
After you select Save, the Gateway service initializes, pulls the image from the cloud or local repository (or transfers the uploaded image file), and initiates the container. Allow some time for the configuration to register, after which Address Manager will redirect you to the server Services tab.
