Deployment pipelines

Edit on GitHub

Spryker Cloud Commerce OS(SCCOS) provides automated CI/CD(Continuous Integration/Continuous Deployment) Pipelines based on the following AWS Code Suite services:

Deployment pipeline types

There are two deployment pipelines: normal and destructive.

Normal deploy is a pipeline that includes all the stages of a complete CI/CD flow. You can set it to run automatically on version control system updates. The install stage of this pipeline does not perform any dangerous data manipulations like database cleanup or scheduler reset. Use it for production deployments.

Destructive deploy is a pipeline that includes all the stages of a complete CI/CD flow. You can set it to run automatically on version control system updates. The install stage of this pipeline resets all the data in applications. Use it for initial or non-production deployments.

Deployment stages

Regardless of the pipeline type, deployment is divided into three stages:

  1. pre-deploy

  2. install

  3. post-deploy

The stages are configured as CodeBuild projects in AWS.

Each stage is configured to execute a set of commands. The configuration is based on two files:

  • buildspec.yml provides the default configuration of SCCOS. This is a CodeBuild configuration file that is used if no custom configuration is provided for a stage.

  • deploy.yml provides a custom configuration overwriting buildspec.yml. This file is located in the project repository root.

Deploy file name

Deploy file name depends on the project and environment you are working with.

The variables in the image: environment: section of deploy.yml are injected into the Docker image built with Spryker Docker SDK.

...
image:
  tag: spryker/php:7.3-alpine3.12
  environment:
    SPRYKER_DEFAULT_STORE: "US"
    SPRYKER_ACTIVE_STORES: "US"
    SPRYKER_HOOK_BEFORE_DEPLOY: "vendor/bin/install -r US/pre-deploy -vvv"
    SPRYKER_HOOK_AFTER_DEPLOY: "true"
    SPRYKER_HOOK_INSTALL: "vendor/bin/install -r US/production --no-ansi -vvv"
    SPRYKER_HOOK_DESTRUCTIVE_INSTALL: "vendor/bin/install -r US/destructive --no-ansi -vvv"
...    

Any shell commands specified in environment variables as hooks are executed with a shell inside the CodeBuild runtime. For example:

...
environment:  
  SPRYKER\_HOOK\_BEFORE\_DEPLOY: “touch /some/file && echo OK || echo FAIL“  
  SPRYKER\_HOOK\_AFTER\_DEPLOY: “curl http://some.host.com:<port>/notify“  
  SPRYKER\_HOOK\_INSTALL: “chmod +x ./some\_custom\_script.sh && ./some\_custom\_scipt.sh“  
  SPRYKER\_HOOK\_DESTRUCTIVE\_INSTALL: “vendor/bin/install -r destructive --no-ansi -vvv“
... 

Pre-deploy stage

The pre-deploy stage is configured as a pre-deploy hook.

pre-deploy-stage

The command or a shell script executed during the pre-deploy stage are set in image: environment: SPRYKER_HOOK_BEFORE_DEPLOY:.

The default command is vendor/bin/install -r pre-deploy -vvv.

The CodeBuild project of this stage is named Run_pre-deploy_for_<project_name>. It uses the currently running application image in the ECS cluster as an environment image, and all Zed environment variables are accessible.

The default configuration in buildspec.yml looks as follows:

pre-deploy-spec

Install stage

The install stage is configured as an install script.

install-stage

Depending on the pipeline type, the install stage command or script is specified in the following variables in deploy.yml:

  • normal: image: environment: SPRYKER_HOOK_INSTALL:

  • destructive: image: environment: SPRYKER_HOOK_DESTRUCTIVE_INSTALL:

The CodeBuild project of this stage is named Run_install_for_<project_name>. The currently built Docker image is used as the environment image and all Zed environment variables are accessible.

The default configuration in buildspec.yml looks as follows:

install-spec

production and destructive refer to the production.yml and destructive.yml install scripts respectively. By default, they are located in config/install.

Post-deploy stage

post-deploy stage is configured as a post-deploy hook.

post-deploy-stage

The command or shell script of the post-deploy stage is set in image: environment: SPRYKER_HOOK_AFTER_DEPLOY:.

The CodeBuild project of this stage is named Run_post-deploy_for_<project_name>. The currently active image is used as the environment image of CodeBuild project and all Zed environment variables are accessible.

The default command just returns true during the post-deploy stage. The default configuration in buildspec.yml looks as follows:

post-deploy-spec
