Command-only deployment package

Create an application and import your Elastic Compute Service (ECS) instances.

1. If you do not have an ECS instance, go to the ECS console - Custom Launch page to create a Linux ECS instance.

   The following example scripts are for these images. If you use a different image, you must modify the scripts accordingly.

2. Go to the ECS console - Application management page and click Create from Existing Resources to create an application and an application group, and import the ECS instance into the application group.

Create a deployment package.

1. Go to the ECS console - Application management page. On the My Applications tab, click the name of your target application.

2. On the application details page, select the Deployment tab, and then click Create Deployment.

3. On the Create Deployment page, set Deployment Package Type to Run Command, configure the parameters, and then click OK.

   • Working directory: Specify the working directory for the startup and shutdown scripts. Example: /root/deploy.

   • Application startup script:

     Alibaba Cloud Linux

     start_application() {
       set -e
       curl -O https://oos-public-cn-hangzhou.oss-cn-hangzhou.aliyuncs.com/code-deploy/sample-spring-1.0-SNAPSHOT.jar
       yum install -y maven-3.5.4
       java -jar ./sample-spring-1.0-SNAPSHOT.jar &
     }
     
     start_application

     Ubuntu

     start_application() {
       set -e
       curl -O https://oos-public-cn-hangzhou.oss-cn-hangzhou.aliyuncs.com/code-deploy/sample-spring-1.0-SNAPSHOT.jar
       apt update
       apt install -y maven
       java -jar ./sample-spring-1.0-SNAPSHOT.jar &
     }
     
     start_application

   • Application shutdown script:

     ### Stop the application (if any)
     stop_application() {
       PID=$(ps -ef | grep "sample-spring-1.0-SNAPSHOT.jar" | grep -v "grep" | awk '{print $2}')
       if [ -n "$PID" ]; then
         kill -9 $PID
       fi
     }
     
     stop_application

Go back to the deployment list, find the deployment that you created, and click Deploy. Select the target group and click OK to start the deployment.

Verify the result.

1. Navigate to the details page of the target instance. Click Connect and select Workbench. Follow the on-screen prompts to access the terminal.

2. Run the curl http://localhost:8080/hello command. A response of Alibaba Spring Sample! indicates a successful deployment.

Prepare the application, group, and ECS instances.

Before you deploy, create an application and a group in ECS Application Management. Then, add your ECS instances to the group.

1. If you do not have an ECS instance, go to the ECS console - Custom Launch page to create a Linux ECS instance.

   The following example scripts are for these images. If you use a different image, you must modify the scripts accordingly.

2. Go to the ECS console - Application management page and click Create from Existing Resources to create an application and an application group, and import the ECS instance into the application group.

3. Install Docker on the ECS instances in the group. On the O&M tab of the application group, select ACS-ECS-BulkyConfigureOOSPackageWithTemporaryURL to install Docker in a batch.

   If your ECS instance was created from a custom image, you cannot install extensions this way. You must remotely connect to the instance and manually install Docker.

Create a deployment package.

1. Pull the sample image to your local machine, and then push the image to your ACR Personal Edition repository.

   docker pull aliyun-computenest-opensource-registry.cn-hangzhou.cr.aliyuncs.com/default/aliyun-code-deploy:latest

2. Go to the ECS console - Application management page. On the My Applications tab, click the name of your target application.

3. On the application details page, select the Parameters tab and click Create Parameter. Create two parameters, username and password, for the ACR Personal Edition username and password. To ensure security, create the password parameter as an encrypted parameter.

4. On the application details page, select the Deployment tab, and then click Create Deployment.

5. On the Create Deployment page, set Deployment Package Type to Run Command, configure the parameters, and then click OK.

   • Working directory: Specify the execution directory for the startup and shutdown scripts. Example: /root/deploy.

   • Application startup script: Replace the <repo> and <image> placeholders with your ACR Personal Edition repository and image details.

     In the following image, the first field is repo, and the second field is image. Replace the corresponding parameters in the application startup script with the values of these two fields.

     ### Start the current version of the application
     start_application() {
        repo="<repo>"
        image="<image>"
        container_name="my-container"
        docker login --username=${username} --password=${password} $repo
        docker pull $image
        docker run -d -p 8080:8080 --name $container_name $image
     }
     
     start_application

   • Application shutdown script:

     ### Stop the container (if any)
     stop_application() {
       # Find the container by name and remove it if it exists.
       container_name="my-container"
       container_id=$(docker ps -aq -f name=${container_name}) 
       if [ -n "$container_id" ]; then
         docker rm -f $container_id
       fi
     }
     
     stop_application

Go back to the deployment list, find the deployment that you created, and click Deploy. Select the target group and click OK to start the deployment.

Verify the result.

1. Navigate to the details page of the target instance. Click Connect and select Workbench. Follow the on-screen prompts to access the terminal.

2. Run the curl http://localhost:8080/hello command. A response of Alibaba Spring Sample! indicates a successful deployment.
