The Portainer Agent and a TLS-protected Docker API both give remote control of a host. The real choice is where the privileged boundary sits and who maintains it.
Stop pasting YAML into your UI. Learn how to use Portainer's Git-based stack deployment to implement a lightweight GitOps workflow for Docker Compose and Swarm.
A diagnostic guide to fixing 'Environment Unavailable' statuses in Portainer by focusing on network blockages, version mismatches, and TLS handshake failures.
Engineering teams often struggle to maintain consistent access control and extensibility across Docker and Kubernetes clusters managed by Portainer. This blog outlines a practical RBAC scoping plugin and version-alignment strategy.
Portainer's Swarm stack deployment turns opaque SSH-and-CLI deploys into a shared, auditable workflow. Here's how it works, a concrete example, and where it falls short.
Learn how to configure Portainer 2.x to expose and control several Docker or Swarm endpoints, secure them with TLS, and scope access with RBAC. Includes a step‑by‑step command example and common pitfalls to avoid.
Stop sharing the Portainer admin account. Here's how to use teams, environments, and least-privilege roles so each team sees and operates only the endpoints it owns — including CI tokens.
Learn how Portainer’s Git‑based Stacks let you version‑control Docker Compose files and automate redeploys on Docker hosts, with a concrete example, trade‑offs, and verification steps.
When a Portainer endpoint shows as unreachable, the problem often lies with the agent container, network path, or TLS settings. This guide walks you through a structured diagnostic flow, concrete checks, fixes, and when to seek support.
