stay organized with collections save and categorize content based on your preferences a valid client certificate must show a chain of trust back to the trust anchor in the trust store this page provides instructions for creating your own trust chain using the root certificate of a private ca certificate authority which is in your control in this setup the private ca is created using the certificate authority service after obtaining the root certificate of the private ca this document outlines the process to upload the certificate to the trust store of the certificate manager trustconfig resource this is followed by linking the trust config to the client authentication servertlspolicy resource and then attaching the client authentication resource to the target https proxy resource of the load balancer before you begin review the mutual tls overview review the guide to manage trust configs install the google cloud cli for a complete overview of the tool see the gcloud cli overview you can find commands related to load balancing in the api and gcloud cli reference if you haven t run the gcloud cli previously first run gcloud init to authenticate review the guide to create a ca pool if you are using global external application load balancer or classic application load balancer make sure you have set up a load balancer with any of the following supported backends vm instance group backends cloud storage buckets supported only if there is at least one backend service also attached to the load balancer in addition to the backend bucket cloud run app engine or cloud run functions hybrid connectivity if you are using regional external application load balancer cross region internal application load balancer or regional internal application load balancer make sure you have set up a load balancer with any of the following supported backends vm instance group backends cloud run hybrid connectivity permissions to get the permissions that you need to complete this guide ask your administrator to grant you the following iam roles on the project to create load balancer resources such as targethttpproxy compute load balancer admin roles compute loadbalanceradmin to use certificate manager resources certificate manager owner roles certificatemanager owner to create security and networking components compute network admin roles compute networkadmin and compute security admin roles compute securityadmin to create a project optional project creator roles resourcemanager projectcreator for more information about granting roles see manage access to projects folders and organizations you might also be able to get the required permissions through custom roles or other predefined roles note iam basic roles might also contain permissions to complete this guide you shouldn t grant basic roles in a production environment but you can grant them in a development or test environment get the root ca s certificate the root ca has a self signed certificate that you need to add to the trust store the root ca s certificate is at the top of the certificate chain to get the root ca s certificate you need to first create a ca pool which is empty on creation you then need create a root ca and add it to the ca pool the root ca and the ca pool is created using the certificate authority service as outlined in the following steps to create a ca pool use the gcloud privateca pools create command gcloud privateca pools create ca_pool location us central1 replace ca_pool with the id or name of the parent ca pool to create a root ca and add it to the ca pool use the gcloud privateca roots create command gcloud privateca roots create ca_root pool ca_pool subject cn my ca o test llc location us central1 replace the following ca_root the id or name of the root ca ca_pool the id or name of the parent ca pool extract the pem encoded certificate that identifies the root ca gcloud privateca roots describe ca_root pool ca_pool location us central1 format value pemcacertificates root cert replace the following ca_root the id or name of the private ca ca_pool the id or name of the parent ca pool the root certificate root cert needs to be uploaded to the trust store this step will be carried out in the following section for more information on using certificate authority service to create a ca pool and a root ca see the following create a ca pool create a root ca format the root ca certificate to include the root certificate in a trust store format the certificate into a single line and store it in an environment variable so that it can be referenced by the trust config yaml file export root cat root cert sed s g tr n sed s n g create a trust config resource a trust config is a resource that represents your public key infrastructure pki configuration in certificate manager to create a trust config resource complete the following steps console in the google cloud console go to the certificate manager page go to certificate manager on the trust configs tab click add trust config enter a name for the configuration for location select global or regional the location denotes where the trust config resource is stored for global external application load balancers classic application load balancers and cross region internal application load balancers create a global trust config resource for regional external application load balancers and regional internal application load balancers create a regional trust config resource if you selected regional select the region in the trust store section click add trust anchor and upload the pem encoded certificate file or copy the contents of the certificate click add click create verify that the new trust config resource appears in the list of configurations gcloud create a trust config yaml file trust_config yaml that specifies the trust config parameters in this example the trust config resource is a trust store with a single trust anchor that represents a root certificate this root certificate is generated using the private ca cat eof trust_config yaml name trust_config_name truststores trustanchors pemcertificate root eof to import the trust config yaml file use the gcloud certificate manager trust configs import command global for global external application load balancers classic application load balancers and cross region internal application load balancers specify global as the location where the trust config resource is stored gcloud certificate manager trust configs import trust_config_name source trust_config yaml location global replace the following trust_config_name the name of the trust config resource regional for regional external application load balancers and regional internal application load balancers specify the region where the trust config resource is stored gcloud certificate manager trust configs import trust_config_name source trust_config yaml location location replace the following trust_config_name the name of the trust config resource location the region where the trust config resource is stored the default location is global create a client authentication resource a client authentication also called servertlspolicy resource lets you specify the server side tls mode and the trust config resource to use when validating client certificates when the client presents an invalid certificate or no certificate to the load balancer the clientvalidationmode specifies how the client connection is handled for more information see mtls client validation modes when the clientvalidationmode is set to allow_invalid_or_missing_client_cert all requests are passed to the backend even if the validation fails or the client certificate is missing when the clientvalidationmode is set to reject_invalid only requests that supply a client certificate that can be validated against a trustconfig resource are passed to the backend to create a client authentication servertlspolicy resource complete the following steps console in the google cloud console go to the authentication configuration page go to authentication configuration on the client authentication tab click create enter a name for the client authentication resource for location select global or regional for global external application load balancers classic application load balancers and cross region internal application load balancers set the location to global for regional external application load balancers and regional internal application load balancers set the location to the region where the load balancer is configured for client authentication mode select load balancing select a client validation mode select the trust config resource that you created earlier optional click equivalent code to view the terraform configuration for this resource click create verify that the client authentication servertlspolicy is displayed gcloud based on how you want to handle the connection select one of the following options to define the client authentication servertlspolicy resource in yaml format option 1 clientvalidationmode is set to allow_invalid_or_missing_client_cert global for global external application load balancers classic application load balancers and cross region internal application load balancers create a yaml file
