organized with collections save and categorize content based on your preferences build and create a java job in cloud run learn how to create a simple cloud run job then deploy from source which automatically packages your code into a container image uploads the container image to artifact registry and then deploys to cloud run you can use other languages in addition to the ones shown before you begin sign in to your google cloud account if you re new to google cloud create an account to evaluate how our products perform in real world scenarios new customers also get 300 in free credits to run test and deploy workloads install the google cloud cli note if you installed the gcloud cli previously make sure you have the latest version by running gcloud components update if you re using an external identity provider idp you must first sign in to the gcloud cli with your federated identity to initialize the gcloud cli run the following command gcloud init create or select a google cloud project roles required to select or create a project select a project selecting a project doesn t require a specific iam role you can select any project that you ve been granted a role on create a project to create a project you need the project creator role roles resourcemanager projectcreator which contains the resourcemanager projects create permission learn how to grant roles note if you don t plan to keep the resources that you create in this procedure create a project instead of selecting an existing project after you finish these steps you can delete the project removing all resources associated with the project create a google cloud project gcloud projects create project_id replace project_id with a name for the google cloud project you are creating select the google cloud project that you created gcloud config set project project_id replace project_id with your google cloud project name if you re using an existing project for this guide verify that you have the permissions required to complete this guide if you created a new project then you already have the required permissions verify that billing is enabled for your google cloud project install the google cloud cli note if you installed the gcloud cli previously make sure you have the latest version by running gcloud components update if you re using an external identity provider idp you must first sign in to the gcloud cli with your federated identity to initialize the gcloud cli run the following command gcloud init create or select a google cloud project roles required to select or create a

project_id replace project_id with your google cloud project name if you re using an existing project for this guide verify that you have the permissions required to complete this guide if you created a new project then you already have the required permissions verify that billing is enabled for your google cloud project enable the cloud run admin api and cloud build apis roles required to enable apis to enable apis you need the serviceusage services enable permission if you created the project then you likely already have this permission through the owner role roles owner otherwise you can get this permission through the service usage admin role roles serviceusage serviceusageadmin learn how to grant roles gcloud services enable run googleapis com cloudbuild googleapis com after the cloud run admin api is enabled the compute engine default service account is automatically created review cloud run pricing or estimate costs with the pricing calculator required roles to get the permissions that you need to complete this quickstart ask your administrator to grant you the following iam roles cloud run admin roles run admin on the project cloud run source developer roles run sourcedeveloper on the project service account user roles iam serviceaccountuser on the service identity logs viewer roles logging viewer on the project 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 grant the cloud build service account access to your project cloud build automatically uses the compute engine default service account as the default cloud build service account to build your source code and cloud run resource unless you override this behavior for cloud build to build your sources grant the cloud build service account the cloud run builder roles run builder role on your project gcloud projects add iam policy binding project_id member serviceaccount service_account_email_address role roles run builder replace project_id with your google cloud project id and service_account_email_address with the email address of the cloud build service account if you re using the compute engine default service account as the cloud build service account then use the following format for the service account email address project_number compute developer gserviceaccount com replace project_number with your google cloud project number for detailed instructions on how to find your project id and project number see creating and managing projects granting the cloud run builder role takes a couple of minutes to propagate writing the sample job to write a job in java create a new directory named jobs and change directory into it mkdir jobs cd jobs in a subdirectory directory named src main java com example create a jobsexample java file for the actual job code copy the following sample lines into it package

allows users to specify the number of tasks the job is to execute this sample code shows how to use the built in cloud_run_task_index environment variable each task represents one running copy of the container note that tasks are usually executed in parallel using multiple tasks is useful if each task can independently process a subset of your data each task is aware of its index stored in the cloud_run_task_index environment variable the built in cloud_run_task_count environment variable contains the number of tasks supplied at job execution time via the tasks parameter the code shown also shows how to retry tasks using the built in cloud_run_task_attempt environment variable which contains the number of times this task has been retried starting at 0 for the first attempt and incrementing by 1 for every successive retry up to max retries the code also lets you generate failures as a way to test retries and to generate error logs so you can see what those look like create a

17 your code is complete and ready to be packaged in a container build jobs container send it to artifact registry and deploy to cloud run this quickstart uses deploy from source which builds the container uploads it to artifact registry and deploys the job to cloud run gcloud run jobs deploy job quickstart source tasks 50 set env vars sleep_ms 10000 set env vars fail_rate 0 1 max retries 5 region region project project_id where project_id is your project id and region is your region for example europe west1 note that you can change the various parameters to whatever values you want to use for your testing purposes sleep_ms simulates work and fail_rate causes x of tasks to fail so you can experiment with parallelism and retrying failing tasks execute a job in cloud run to execute the job you just created gcloud run jobs execute job quickstart region region replace region with the region you used when you created and deployed the job for example europe west1 success you created and executed a job using the java runtime in cloud run clean up to avoid additional charges to your google cloud account delete all the resources you deployed with this quickstart delete your repository cloud run only charges for the time your job executes however you might still be charged for storing the container image in artifact registry to delete artifact registry repositories follow the steps in delete repositories in the artifact registry documentation delete your job cloud run jobs only incur cost when a job task is executing to delete your cloud run job follow one of these steps console to delete a job in the google cloud console go to cloud run go to cloud run locate the job you want to delete in the jobs list and click its checkbox to select it click delete this terminates all the job executions in progress and all running container instances gcloud to delete a job run the following command gcloud run jobs delete job_name replace job_name with the name of the job delete your test project deleting your google cloud project stops billing for all resources in that project to release all google cloud resources in your project follow...
