📖 What Does This Skill Do?

The Portainer Skill gives you control over your Docker infrastructure through Portainer's REST API. Manage containers, stacks, and deployments without touching the web UI.

Features:

• 📊 Status — Check Portainer server status
• 🖥️ Endpoints — List all Docker environments
• 📦 Containers — List, start, stop, restart containers
• 📚 Stacks — List and manage Docker Compose stacks
• 🔄 Redeploy — Pull from git and redeploy stacks
• 📜 Logs — View container logs

---

⚙️ Requirements

What	Details
Portainer	Version 2.x with API access
Tools	curl, jq
Auth	API Access Token

Setup

1. Get API Token from Portainer:

   • Log into Portainer web UI
   • Click username → My Account
   • Scroll to "Access tokens" → Add access token
   • Copy the token (you won't see it again!)

2. Configure credentials:

   # Add to ~/.thinkfleetbot/.env
   PORTAINER_URL=https://your-portainer-server:9443
   PORTAINER_API_KEY=ptr_your_token_here
   

3. Ready! 🚀

This will:

1. Pull latest code from git
2. Rebuild containers if needed
3. Restart the stack

---

start / stop / restart — Container Control

# Start a container
./portainer.sh start steinbergerraum-web-1

# Stop a container
./portainer.sh stop steinbergerraum-web-1

# Restart a container
./portainer.sh restart steinbergerraum-web-1

# Specify endpoint (default: 4)
./portainer.sh restart steinbergerraum-web-1 4

Output:

✓ Container 'steinbergerraum-web-1' restarted

---

🎯 Example Workflows

🚀 "Deploy Website Update"

# After merging PR
./portainer.sh redeploy 25
./portainer.sh logs steinbergerraum-web-1 4 20

🔧 "Debug Container"

./portainer.sh containers
./portainer.sh logs cora-web-1
./portainer.sh restart cora-web-1

📊 "System Overview"

./portainer.sh status
./portainer.sh endpoints
./portainer.sh containers
./portainer.sh stacks

---

🔧 Troubleshooting

❌ "Authentication required / Repository not found"

Problem: Stack redeploy fails with git auth error

Solution: The stack needs repositoryGitCredentialID parameter. The script handles this automatically by reading from the existing stack config.

---

❌ "Container not found"

Problem: Container name doesn't match

Solution: Use exact name from ./portainer.sh containers:

• Include the full name: steinbergerraum-web-1 not steinbergerraum
• Names are case-sensitive

---

❌ "PORTAINER_URL and PORTAINER_API_KEY must be set"

Problem: Credentials not configured

Solution:

# Add to ~/.thinkfleetbot/.env
echo "PORTAINER_URL=https://your-server:9443" >> ~/.thinkfleetbot/.env
echo "PORTAINER_API_KEY=ptr_your_token" >> ~/.thinkfleetbot/.env
