Operations Specification (ops-spec.json)

Several third-party dependencies are required to build and deploy the Elastic Path Commerce source code. These are documented in Supported Technologies. However, rather than hard-coding these dependencies into operations tooling, the Elastic Path Commerce source provides a machine-readable file with these details for use by build and deployment tools, such as CloudOps for Kubernetes.

File Specification

The machine-readable operations specification file is in JSON format. It has the following structure:

• java
  • version: The Java version required for builds and at runtime.
  • downloadUrl: The URL to download a Linux x86 64-bit module of the Azul Zulu JDK.
  • downloadChecksum: A SHA1 checksum of the downloaded file for tamper verification.
  • path: The expected path to the JDK once the module is installed.
  • jvmRuntimeArguments: The JVM arguments that should be passed to the application server at runtime.
• maven
  • version: The Maven version required for builds.
  • downloadUrl: The URL to download a tar gunzip archive of Maven.
  • downloadChecksum: A SHA1 checksum of the downloaded file for tamper verification.
  • path: The expected path contained within the tar archive.
• applicationServer
  • version: The Tomcat version required at runtime.
  • downloadUrl: The URL to download a tar gunzip archive of Tomcat.
  • downloadChecksum: A SHA1 checksum of the downloaded file for tamper verification.
• activemq
  • version: The ActiveMQ version required at runtime.
  • downloadUrl: The URL to download a tar gunzip archive of ActiveMQ.
  • downloadChecksum: A SHA1 checksum of the downloaded file for tamper verification.
• databases
  • Array of database options with the following structure:
    • id: A unique identifier for the database option.
    • type: The database type; usually mysql, postgresql, or oracle.
    • deployment: The AWS deployment option; usually rds or aurora.
    • versionChoice: The database version choice for the user. Not a complete version specification; just what is needed to provide the user with a version choice.
    • mavenProfile: The Maven profile to pass to the build for using this database in a development environment.
    • awsDbEngine: The database engine version supported by the AWS. The parameter value must be accurate per AWS documentation. See the "EngineVersion" section of AWS::RDS::DBInstance.
• healthchecks
  • readinessPath: The path to the health check readiness endpoint for an Elastic Path web app.
  • livenessPath: The path to the health check liveness endpoint for an Elastic Path web app.

Availability

The ops-spec.json file can be accessed from two locations:

• In the devops/ops-spec/src/main/resources/ops-spec.json file in the ep-commerce source code repository, and is the primary instance.
• A copy of the above file is put into ops-spec.json in the root of the deployment package at build time.
