copilot-cli: Release v1.14.0

⚡️ Features and enhancements

• Enable Network Load Balancer (#3142)

  You can enable Network Load Balancer for your Load-Balanced Web Service simply by adding nlb to your manifest, for example:

  nlb:
     port: 80/tcp # or tls

  You can then access your service through Network Load Balancer via its DNS name.

  Expand for additional NLB configuration

  If your application is associated with a domain, then Copilot will give your service a default alias of <service>-nlb.<environment>.<app>.<domain>. Similar to today's http field, you can take advantage of the alias field to change this behavior:

  nlb:
      port: 80/tcp
      alias: ["example.com", "v1.example.com"]

  In this way, your service will be accessible through "example.com:80" and "v1.example.com:80" with tcp protocol.

  Moreover, you can also enable TLS termination by

  nlb:
     port: 443/tls

  It is also possible to use only the Network Load Balancer - without the Application Load Balancer - for your Load-Balanced Web Service:

    http: false
    
    nlb:
       port: 80/tcp

• Support external files for environment variables (#3138)

  More efficiently use and reuse multiple env vars by keeping them in a .env file. In your workload manifest:

  env_file: <path>

  You can specify different env vars per environment with env overrides:

  env_file: <test path>
  environment:
    prod:
      env_file: <prod path>

• Provide the option to use CloudWatch Container Insights (#3126)

  When creating a new environment, use the new --container-insights flag to collect those metrics:
  copilot env init --container-insights

• Check if associated domains are not registered with Route 53 and recommend actions accordingly (#3081)

• Allow more than two availability zones when configuring the default environment in copilot env init (#3131)

• Rename pipeline update to pipeline deploy (#3154)

🐛 Bug Fixes

• Error out when trying to initialize preexisting environments (#3088) or services/jobs (#3116)
• Enable the --force flag with copilot svc deploy when Auto Scaling is set (#3127)
• Detect ARM-based CodeBuild images in the pipeline manifest and automatically change the build environment type (#3190)
• Exit the pipeline build stage if workload manifests don't pass validations (#3080)
