Epoch-dd-agent build instructions

1.Perform below steps from root of this repo . Below are bat format commands .

• call berks
• call berks vendor
• move berks-cookbooks cookbooks

2. Run ./run.bat to set environment and build dd-agent and generate a .msi and .exe at C:\omnibus-ruby\pkg location.

Note: DD-agent section follows

dd-agent-builder cookbook

Used to build the agent on Windows. Heavily relies on the Chef Omnibus cookbook.

It has two recipes. The default recipes runs prepare then build.

dd-agent-builder::prepare

Installs Golang and all the dependencies of Omnibus, and downloads dd-agent-omnibus.

dd-agent-builder::build

Builds the agent (with the omnibus_build resource from the omnibus cookbook).

Setting custom parameters

Variables to build an agent are pulled from release.json from dd-agent-omnibus. Those variables are used to pin version of the agent dependencies.

By default the job will use dd-agent-omnibus's master and nightly from release.json.

Pulling a specific version of dd-agent-omnibus

You can choose a specific branch, tag or commit by setting the environment variable DD_AGENT_OMNIBUS_BRANCH.

Building a specific version of the agent

Instead of building nightly you can choose a version from release.json by setting the environment variable RELEASE_VERSION.

Local overwrite

You can overwrite the following variables by setting them manually in attributes.json (useful for local dev):

• dd-agent-omnibus_branch : git version of dd-agent-omnibus to use
• dd-agent_branch : git version of dd-agent repo to use
• omnibus-ruby_branch : git version of omnibus-ruby to use (DataDog fork)
• omnibus-software_branch : git version of omnibus-software to use (DataDog fork)
• integrations-core_branch : git version of integrations-core to use
• trace-agent_branch : git version of trace-agent to use
• agent_version : The agent version targeted
• agent6_branch : git revision of datadog-agent repo to use (for dogstatsd 6)
• trace_agent_add_build_vars :
• process_agent_branch : The version of the process agent to ship

Variables are first loaded from the release.json and then overwritten by attributes.json.

example of attributes.json:

{
  "dd-agent-builder": {
    "dd-agent-omnibus_branch": "master",
    "dd-agent_branch": "5.21.0",
    "omnibus-ruby_branch": "master",
    "omnibus-software_branch": "master",
    "integrations-core_branch": "custom-postgres-branch",
    "trace-agent_branch": "master"
  },
  "omnibus": {
  }
}
