It is very important that you follow the instructions to turn down the cluster if you do not want to continue to be billed for these resources. [This calculator quote](https://cloud.google.com/products/calculator/#id=4539f510-f60f-4479-a686-5a4a37896368) provides an estimate of the monthly cost of the resources provisioned in this example. 11 | 12 | Be sure to create a brand new project for this tutorial (instructions are in the deploy sections below). Also be sure to complete the [Delete the Deployment](#delete-the-deployment) section when you're done. It's super quick and will tear down everything you created. 13 | 14 | ## Conventions 15 | The instructions in this tutorial assume you have access to a terminal on a Linux or OS X host. For Windows hosts, [Cygwin](http://cygwin.com/) should work. 16 | 17 | You will need to enter commands in your terminal. Those commands are indicated in the following format, where `$` indicates a prompt (do not paste the $ into your terminal, just everything that follows it): 18 | 19 | ```shell 20 | $ echo "This is a sample command" 21 | ``` 22 | ## Deploy 23 | ### Deployment Requirements 24 | Before you deploy the sample you'll need to make sure a few things are in order: 25 | 26 | 1. Create a new project in the [Google Developer Console](https://console.developers.google.com/project) and note the new project's ID. 27 | 28 | 1. In the [APIs & Auth section of the Google Developers Console](https://console.developers.google.com/project/_/apiui/api) of your new project, enable the following APIs: 29 | 30 | * Google Compute Engine 31 | * Google Kubernetes Engine API 32 | * Cloud Build API 33 | 34 | 1. Install the Cloud SDK verssion `0.9.68` or greater using [these instructions](https://cloud.google.com/sdk/). 35 | 36 | 1. Authenticate to gcloud: 37 | 38 | ```shell 39 | $ gcloud auth login 40 | ``` 41 | 42 | 1. Set your project: 43 | 44 | ```shell 45 | $ gcloud config set project YOUR_PROJECT_ID 46 | ``` 47 | 48 | 1. Enable `kubernetes` features: 49 | 50 | ```shell 51 | $ gcloud components update kubectl 52 | ``` 53 | 54 | 1. If you are using Windows to complete the tutorial, install [Cygwin](http://cygwin.com/) and execute the steps in a terminal. 55 | 56 | 57 | ### Quick Deploy 58 | These quick deploy instructions are easiest way to get started. The work to create a Google Kubernetes Engine cluster and launch the necessary Kubernetes resources is captured in the `cluster_up.sh` script. 59 | 60 | To quick deploy the image builder application: 61 | 62 | 1. Clone this repository (`$ git clone https://github.com/GoogleCloudPlatform/kube-jenkins-imager.git`) or download and unzip a [copy from releases](https://github.com/GoogleCloudPlatform/kube-jenkins-imager/releases). 63 | 64 | 1. Navigate to the directory: 65 | 66 | ```shell 67 | $ cd kube-jenkins-imager 68 | ``` 69 | 70 | 1. From a terminal in the directory you cloned or unzipped, run: 71 | 72 | ```shell 73 | $ ./cluster_up.sh 74 | ``` 75 | 76 | The script will take several minutes to complete. The abbreviated output should look similar to: 77 | 78 | ```shell 79 | Creating cluster imager...done. 80 | ... 81 | ... 82 | 83 | ... 84 | ... 85 | All resources deployed. 86 | ``` 87 | 1. Continue to the [Access Jenkins](#access-jenkins) section (skip the Stepwise Deploy section) 88 | 89 | 90 | ### Stepwise Deploy 91 | You can find open the `cluster_up.sh` script and execute the commands from each line for a closer look at everything that's taking place. 92 | 93 | 94 | ## Access Jenkins 95 | 1. Access the URL output when you created your deployment. Click the login button and use the username and password 96 | that was output by the `cluster_up.sh` script: 97 | 98 | 1. After a successful login you should see the Jenkins admin landing page: 99 | 100 | ![](img/jenkins.png) 101 | 102 | ## Configure Jenkins 103 | In the following sections you will create a credential, define and run an image build job, and backup the Jenkins configuration. 104 | 105 | ### Create Credentials 106 | 1. **Optional:** Configure a Jenkins login (in addition to the basic access authentication at the reverse proxy) by navigating to **Manage Jenkins >> Configure Global Security** and configuring authentication and authorization settings to your requirements 107 | 108 | 1. Create a credential by clicking on the **Credentials** link in the left nav, then clicking the **Global credentials** link: 109 | 110 | ![](img/creds-link.png) 111 | 112 | 1. Click **Add Credentials** in the left nav, choose `Google Service Account from metadata` in the **Kind** dropdown, and click **OK**. The Project Name will be auto-populated: 113 | 114 | ![](img/creds-add.png) 115 | 116 | ### Create and Run a Build Job 117 | In the following sections you will clone an existing repo (from the previous [Scalable and Resilient Web Applications](https://github.com/GoogleCloudPlatform/scalable-resilient-web-app) tutorial that includes a working build configuration. You will then push that repo to your project's Cloud Repository, create a Jenkins job to build it, and run the job. 118 | 119 | #### Replicate a GitHub Repo 120 | 1. Clone the existing sample repository to your workstation (you must have `git` installed) and go into the new directory: 121 | 122 | ```shell 123 | $ git clone https://github.com/GoogleCloudPlatform/scalable-resilient-web-app.git 124 | $ cd scalable-resilient-web-app 125 | ``` 126 | 127 | 1. Create a Cloud Source Repository and push your code to it: 128 | 129 | ```shell 130 | $ gcloud source repos create scalable-resilient-web-app 131 | $ git config --global credential.https://source.developers.google.com.helper gcloud.sh 132 | $ export PROJECT=$(gcloud config get-value project) 133 | $ git remote add google https://source.developers.google.com/p/${PROJECT}/r/scalable-resilient-web-app 134 | $ git push --all google 135 | ``` 136 | 137 | 1. After you've pushed your files to the Cloud Source Repository, find and copy its Fetch URL for use in the next section: 138 | 139 | ```shell 140 | $ git remote -v show -n google | grep Fetch 141 | Fetch URL: https://source.developers.google.com/p/your-new-project/ 142 | ``` 143 | 144 | **Note:** The URL should be your project ID appended to the string `https://source.developers.google.com/p/` 145 | 146 | 147 | #### Create Jenkins Job 148 | 1. Access Jenkins in your browser. If you don't remember the URL, you can run the following command in the terminal where you created the deployment to find it: 149 | 150 | ```shell 151 | $ echo http://$(kubectl get service cd-jenkins -o "jsonpath={.status.loadBalancer.ingress[0].ip}") 152 | ``` 153 | 154 | 1. From the Jenkins main page, choose **New Item*, name the item `redmine-immutable-image`, choose **Pipeline**, then click **OK**. It is important the name does not include spaces. 155 | 156 | ![](img/jenkins-trigger.png) 157 | 158 | 1. Under **Build Triggers**, choose Poll SCM and enter a value for Schedule. In this example, `H/5 * * * *` will poll the repository every 5 minutes. Choose a value that you consider appropriate: 159 | 160 | ![](img/jenkins-trigger.png) 161 | 162 | 1. Under **Pipeline**, in the **Definition** dropdown choose **Pipeline script from SCM**. 163 | 164 | 1. Paste your Cloud Repository URL (`https://source.developers.google.com/p/your-project-id`) from the previous section, and choose the credential you created earlier from the dropdown: 165 | 166 | ![](img/jenkins-scm.png) 167 | 168 | 1. Click Save to save your job. 169 | 170 | #### Run the Build 171 | 1. After saving the project, choose the **Build Now** menu item, then click the job number when it appears: 172 | 173 | ![](img/jenkins-build-now.png) 174 | 175 | 1. Choose the **Console Output** menu item and observe the job's progress: 176 | 177 | ![](img/jenkins-console-output.png) 178 | 179 | Jenkins parallelizes the GCE and Docker builds. You can expect the build to take about 20 minutes; the sample build is updating the OS, building and installing Ruby, and installing the Redmine project management application and all of its gem dependencies. 180 | 181 | 1. The build is done when you see a `Finished: SUCCESS` line in the output. A few lines before that you should see the outputs (GCE and Docker iamges) of the build: 182 | 183 | ```shell 184 | ==> Builds finished. The artifacts of successful builds are: 185 | --> googlecompute: A disk image was created: redmine-1431028076-master-c84d21f 186 | --> docker: Imported Docker image: 0717053a7fce3c637a5bfd887954f41b4327e80493eb6492277e2dbb132c2bf4 187 | --> docker: Imported Docker image: gcr.io/your-new-project/redmine:master-c84d21f 188 | ... 189 | ... 190 | Finished: SUCCESS 191 | ``` 192 | 193 | 1. In the [Google Developers Console](https://console.developers.google.com) navigate to **Compute > Images** and confirm that your GCE image for Redmine is there: 194 | 195 | ![](img/view-image.png) 196 | 197 | 198 | ## Delete the Deployment 199 | It is very important (as mentioned in the [Very Important Things](#very-important-things) section of this document) that you delete your deployment when you are done. You will be charged for any running resources. 200 | 201 | Whether you followed the [Quick Deploy](#quick-deploy) or [Stepwise Deploy](#stepwise-deploy) instructions, deleting resources is very easy. Simply delete the project you created at the beginning of this tutorial: 202 | 203 | 1.
