-# netoik-rp
+# Netoïk reverse proxy ![badge](https://git.netoik.io/samuel/netoik-rp/actions/workflows/ci.yaml/badge.svg)
 
-Netoïk reverse proxy
+Build an RPM package which will install several tools.
+
+- `Nginx` with:
+    - ssl settings
+    - security headers
+    - default site configuration
+
+
+- `Certbot` certificates with:
+    - ovh configuration to renew certs
+    - a command tool certbot_renew
+    - a systemctl certbot renew timer
+
+
+# Development
+
+A `Makefile` is integrated to let you run some basic commands.
+
+- To display some information about the project
+  ```shell
+  make name
+  make version
+  make release
+  make build_arch
+  ```
+
+- To build a tarball:
+  ```shell
+  make tarball 
+  ```
+  
+- To build a rpm package:
+  ```shell
+  rpmbuild -ba netoik-rp.spec
+  ```
+  
+- To upload rpm package to Gitea repository
+(env vars `GIT_PACKAGES_USERNAME` and `GIT_PACKAGES_TOKEN` needed):
+  ```shell
+  make upload
+  ```
+
+
+# CI / CD
+
+Two workflows are set up.
+
+- Continuous Integration:
+  - triggered by each push on branch `main`
+  - runs shellcheck on script `certbot_renew`
+  - builds tarball and rpm package to test everything is OK
+
+
+- Continuous Delivery:
+  - triggered by each tag pushed
+  - builds tarball
+  - builds and uploads rpm package to `Gitea` repository
+
+
+# Deployment
+
+Some commands to deploy the RPM package on server
+
+- To add Gitea repo to your repo list:
+  ```shell
+  dnf config-manager --add-repo https://git.netoik.io/api/packages/samuel/rpm.repo
+  dnf repolist | grep gitea-samuel
+  ```
+  
+- To show available versions:
+  ```shell
+  dnf --showduplicates netoik-rp
+  ```
+  
+- To install or upgrade:
+  ```shell
+  dnf --nogpgcheck install netoik-rp
+  dnf --nogpgcheck upgrade netoik-rp
+  ```
+
+
+# Security Notes
+
+For security reasons, act runners does not have sudo privileges and so there is:
+- **no** Continuous Deployment because act runners cannot use `dnf`
+- **no** GPG signing because act runners cannot use `gpg`
