v1.5.0: Prometheus monitoring support

Breaking Changes

In this release we unified how you should specify resources for browser images in browsers.json and service images in service.json files. You can now specify requests and limits in service.json file as follows:

Before:

{
  "images": {
    "logger": {
      "image": "my-registry.example.com/moon/logger:latest-release",
      "cpu": "0.3",
      "mem": "1024Mi"
    }
  }
}

Now:

{
  "images": {
    "logger": {
      "image": "my-registry.example.com/moon/logger:latest-release",
      "resources": {
        "limits": {
          "cpu": "0.3",
          "memory": "1024Mi"
        },
        "requests": {
          "cpu": "0.3",
          "memory": "1024Mi"
        }
      }
    }
  }
}

Security Changes

In previous releases all browsers pods by default were created with SYS_ADMIN Linux kernel capability. To work in restricted environments starting from this release by default browser pods are created without this capability. This change mainly influences working with Chromium-based browsers. You have two options:

Option 1. Configure Moon to continue running all browser pods with SYS_ADMIN kernel capability. To have this option - just add the following to Moon service.json configuration file:

{
  "kernelCaps": [ "SYS_ADMIN" ]
}

This is what we do by default in our official deployment manifests.

Option 2. Start Chrome with --no-sandbox flag from your test code.

Known Update Issues

When doing a rolling update from 1.4.x series you can see the following messages in moon-api log:

2020/05/21 14:54:45 [STATUS_REQUEST_ERROR] [127.0.0.1] [parse enableVideo: strconv.ParseBool: parsing "": invalid syntax]

These messages will disappear as soon as browser pods created by 1.4.x are deleted.
