+In production, TLS certificates are typically issued by a trusted Certificate Authority (for example, via Let’s Encrypt).
+For local development and demo environments, a self-signed certificate can be used.
+
+## Generate a self-signed certificate (Linux/macOS)
+From the repository root:
+
+```bash
+mkdir -p deploy/shagram/nginx/certs
+
+openssl req -x509 -newkey rsa:4096 \

+```
+
+## Verify
+```bash

+# Jenkins (Controller + Docker Agent) Setup (Docker Compose)
+
+This directory contains a minimal Jenkins setup using a dedicated **controller** and a separate inbound **agent** intended for Docker-based workloads.
+
+The goal is to keep the controller responsible for orchestration and configuration, while all builds run on the agent labeled `docker`.
+
+## Prerequisites
+- Docker Engine installed on the host
+- Docker Compose available as `docker compose`
+- A host directory `/opt/shagram` (used by pipelines as a shared location for source code and deployment files)
+
+## Start Jenkins
+From the repository root:
+
+```bash
+cd infra/jenkins
+docker compose up -d
+docker compose ps
+```
+
+Jenkins UI will be available at:
+
+- http://<server-ip>:8080
+
+### Initial admin password
+Retrieve the initial password with:
+
+```bash
+docker exec -it jenkins-controller cat /var/jenkins_home/secrets/initialAdminPassword
+```
+
+## Disable builds on the built-in node (Executors = 0)
+To ensure builds do not run on the controller:
+
+1. Open Jenkins UI
+2. Go to: **Manage Jenkins → Manage Nodes and Clouds**
+3. Open **Built-In Node → Configure**
+4. Set **Number of executors** to `0`
+5. Save
+
+## Create an inbound agent node (docker-agent)
+Create a dedicated node for running pipelines:
+
+1. Go to: **Manage Jenkins → Manage Nodes and Clouds → New Node**
+2. Set:
+   - **Node name**: `docker-agent`
+   - **Type**: Permanent Agent
+   - **Remote root directory**: `/home/jenkins/agent`
+   - **Labels**: `docker`
+   - **Usage**: Only build jobs with label expressions matching this node
+3. Save
+
+After saving, open the agent page:
+
+- **Manage Nodes and Clouds → docker-agent**
+
+On that page, Jenkins provides the inbound connection details, including the **secret** required by the inbound agent container.
+
+## Configure the agent secret in Compose
+Edit `infra/jenkins/compose.yaml` and replace:
+
+- `JENKINS_SECRET=__PASTE_ME__`
+
+with the real secret value shown on the `docker-agent` node page.
+
+Restart only the agent container:
+
+```bash
+docker compose up -d --force-recreate jenkins-agent-docker
+docker logs -f jenkins-agent-docker
+```
+
+## Verification
+- In Jenkins UI: **Manage Nodes and Clouds**, the node `docker-agent` should be **Online**
+- Any pipeline using `agent { label 'docker' }` should execute on this agent
+
+## Security note
+The Docker agent container mounts `/var/run/docker.sock`, which effectively grants high-level control over the Docker host. Use this setup only in trusted environments and limit access to Jenkins accordingly.
