Update a connector

Follow these steps to update a connector:

1. Copy the following Account level or Organization level AWS update script. Be sure to replace AWS_STACK_NAME with your AWS stack name.

Account Level

aws cloudformation update-stack --stack-name AWS_STACK_NAME \
    --template-url https://apono-public.s3.amazonaws.com/cloudformation/aws_integration_with_connector_template.yml \
    --parameters ParameterKey=AponoConnectorId,UsePreviousValue=true \
                 ParameterKey=AponoConnectorToken,UsePreviousValue=true \
                 ParameterKey=ExternalID,UsePreviousValue=true \
                 ParameterKey=SubnetIDs,UsePreviousValue=true \
                 ParameterKey=VpcId,UsePreviousValue=true \
    --capabilities CAPABILITY_NAMED_IAM

Organizational Level

aws cloudformation update-stack --stack-name AWS_STACK_NAME --template-url https://apono-public.s3.amazonaws.com/cloudformation/aws_organization_integration_template.yml \
    --parameters ParameterKey=AponoConnectorId,UsePreviousValue=true \
                 ParameterKey=AponoConnectorToken,UsePreviousValue=true \
                 ParameterKey=AssignPublicIp,UsePreviousValue=true \
                 ParameterKey=ExternalID,UsePreviousValue=true \
                 ParameterKey=OrganizationalUnitId,UsePreviousValue=true \
                 ParameterKey=SubnetIDs,UsePreviousValue=true \
                 ParameterKey=VpcId,UsePreviousValue=true \
    --capabilities CAPABILITY_NAMED_IAM

export stackSetName=$(
aws cloudformation describe-stack-resources \
    --stack-name AWS_STACK_NAME \
    --logical-resource-id CrossAccountReadOnlyRoleStackSetResource \
    --query "StackResources[0].PhysicalResourceId" \
    --output text)

aws cloudformation update-stack-set --stack-set-name $stackSetName --template-url https://apono-public.s3.amazonaws.com/cloudformation/aws_integration_read_only_template.yml \
    --parameters ParameterKey=ExternalID,UsePreviousValue=true \
                 ParameterKey=AponoConnectorId,UsePreviousValue=true \
                 ParameterKey=AponoConnectorRoleArn,UsePreviousValue=true \
    --capabilities CAPABILITY_NAMED_IAM

If you have not defined a default region and default profile, you must specify the region and profile in the script:

--profile AWS_PROFILE --region AWS_SERVER_REGION

Be sure to replace AWS_PROFILE and AWS_SERVER_REGION with your profile and region values.

1. At your AWS CLI prompt, enter the updated script from the previous step to initiate the update. The AWS CLI will return an object containing the StackId.

2. In CloudFormation, on the Stack Info tab, confirm that the update has completed:

   1. Go to the Stacks page. A list of the stacks in the account are displayed.
   2. Under the Stack name column, click the stack name.

   3. On the Stack info tab, check the Status.

Troubleshooting

This section details common errors that can occur during the updating process. If an error occurs that is not listed below, please contact your Apono representative.

An error occurred (ValidationError) when calling the UpdateStack operation: Stack [stack name] does not exist.

This occurs when the incorrect stack name has been included in the update script.

Use the following steps to correct this error:

1. Locate and copy the stack name under the Stack name column of the Stacks page.
2. Repeat the update process.
