agent-install

Install the Datadog Agent on Kubernetes

Before doing anything else: Fully resolve all variables in ## Context to resolve before acting. Do not begin Step 1 until every variable has a concrete value.

Phase 0: Load Credentials

[ -f environment ] && source environment
echo "DD_API_KEY set: $([ -n "${DD_API_KEY:-}" ] && echo yes || echo no)"
echo "DD_SITE: ${DD_SITE:-not set}"
echo "helm: $(helm version --short 2>/dev/null || echo NOT FOUND)"

If helm is not found — tell the user:

helm is required for this skill. Install it with:

brew install helm        # macOS
# or see https://helm.sh/docs/intro/install/ for other platforms

Once installed, let me know and I'll continue.

Do not proceed until helm is available.

If DD_API_KEY is already set — proceed to Prerequisites.

If DD_API_KEY is not set — tell the user:

I need two things to continue:

1. Datadog API Key — used to authenticate the Agent with your Datadog account. You can find or create one at: https://app.datadoghq.com/organization-settings/api-keys

2. Datadog Site — the region your Datadog account is on. Most accounts use datadoghq.com. Check your Datadog URL to confirm (e.g. app.datadoghq.eu → site is datadoghq.eu). Other options: us3.datadoghq.com, us5.datadoghq.com, ap1.datadoghq.com.

Please run the following in this chat to set your credentials (the ! prefix executes it in this session):

! export DD_API_KEY=your-api-key-here
! export DD_SITE=datadoghq.com

Wait for the user to run the commands, then re-run the check above before continuing.

Prerequisites

• Kubernetes v1.20+ — kubectl version
• helm v3+ — helm version
• kubectl configured to target cluster — kubectl config current-context
• pup-cli installed — check with pup --version; if missing, install it now:

  if [[ "$(uname)" == "Darwin" ]]; then
    brew tap datadog-labs/pack && brew install pup
  else
    PUP_VERSION=$(curl -s https://api.github.com/repos/datadog-labs/pup/releases/latest | grep '"tag_name"' | cut -d'"' -f4)
    curl -L "https://github.com/datadog-labs/pup/releases/download/${PUP_VERSION}/pup_linux_amd64.tar.gz" | tar xz -C /usr/local/bin pup
    chmod +x /usr/local/bin/pup
  fi
  pup --version
  

  Do not skip — proceed only once pup --version succeeds.
