Argo CD Pipeline Tasks

Azure Pipelines tasks for Argo CD that talk to the Argo CD REST API directly — no CLI download, no gRPC, no 240 MB per pipeline run.

Available on the Marketplace

Install the extension — six tasks, tested against live Argo CD 3.3, 3.4 and 3.5.

Why this exists

The Marketplace alternatives are a sync-only task last verified against Argo CD 1.6, and a closed-source extension with no public repository. Most teams end up hand-rolling argocd app sync plus argocd app wait in a script step, which means downloading a ~240 MB CLI binary on every hosted-agent run and debugging gRPC through their ingress.

These tasks call the Argo CD REST gateway over ordinary HTTPS instead.

• Nothing to download. Pure Node, so air-gapped and self-hosted agents work unchanged.
• No gRPC ingress problems. No HTTP/2 requirement, no --grpc-web, no --grpc-web-root-path.
• Built for pipelines. Typed output variables, a Markdown run summary with an application table and a rendered diff, and task results that tell "degraded" apart from "still progressing".

The tasks

Task	What it does
ArgoCDApp@1	Get status, sync, wait, diff, roll back, run resource actions, collect logs and manifests, create, set/unset and delete applications.
ArgoCDAppSet@1	Manage ApplicationSets and preview the Applications they generate.
ArgoCDProject@1	Read projects; mint and revoke project role tokens.
ArgoCDAccount@1	Manage local account tokens, and check what a token may do.
ArgoCDInstall@1	Download, verify and cache the argocd CLI.
ArgoCDCli@1	Run any argocd command with authentication injected.

Reach for ArgoCDApp@1 first. The CLI tasks are the escape hatch for what REST cannot do: app diff --local, --core mode, admin subcommands, and features newer than this extension.

Quick start

Add an Argo CD service connection, then:

- task: ArgoCDApp@1
  displayName: Deploy payments
  inputs:
    connection: 'argocd-prod'
    command: 'sync'
    applications: 'payments-api'
    project: 'payments'
    prune: true
    syncOptions: |
      CreateNamespace=true
      ServerSideApply=true
    wait: true
    waitFor: 'sync,health'
    timeoutSeconds: '600'

Compatibility

Argo CD	3.3, 3.4, 3.5 — the versions upstream supports
Agents	Windows, Linux, macOS; hosted, self-hosted, Managed DevOps Pools
Node handler	Node24, falling back to Node20_1; minimum agent 4.248.0

The client is verified against the Argo CD OpenAPI spec for the oldest supported minor by a contract test, and exercised against real Argo CD 3.3, 3.4 and 3.5 servers in CI — so an upstream change fails the build rather than a deployment.
