Clear Linux* OS nginx container image

What is this image?

clearlinux/nginx is a Docker image with nginx running on top of the official clearlinux base image.

Nginx (pronounced "engine-x") is an open source reverse proxy server for HTTP, HTTPS, SMTP, POP3, and IMAP protocols, as well as a load balancer, HTTP cache, and a web server (origin server).

Why use a clearlinux based image?

Clear Linux* OS is an open source, rolling release Linux distribution optimized for performance and security, from the Cloud to the Edge, designed for customization, and manageability.

Clear Linux* OS based container images use:

• Optimized libraries that are compiled with latest compiler versions and flags.
• Software packages that follow upstream source closely and update frequently.
• An aggressive security model and best practices for CVE patching.
• A multi-staged build approach to keep a reduced container image size.
• The same container syntax as the official images to make getting started easy.

Deployment:

Deploy with Docker

The easiest way to get started with this image is by simply pulling it from Docker Hub.

Note: This container uses the same syntax as the official nginx image. The default root path is /var/www/html and default configuration path is /etc/nginx/.

1. Pull the image from Docker Hub:

   docker pull clearlinux/nginx
   

2. Start a container using the examples below:

   • Start with persistent volume for web content:

     docker run -p 80:80 -v /some/content:/var/www/html -d clearlinux/nginx
     

   • Start with an alternative nginx configuration file:

     docker run -p 80:80 -v /host/path/nginx.conf:/etc/nginx/nginx.conf -d clearlinux/nginx
     

Deploy with Kubernetes

This image can also be deployed on a Kubernetes cluster, such as minikube.The following example YAML template files are provided in the repository as reference for Kubernetes deployment:

• nginx-service-deployment-simple.yaml: example using default configuration to create a basic nginx service.
• nginx-service-deployment-customize-conf.yaml: example using a customized nginx.conf configuration file to replace default one.
• nginx-service-deployment-persistent-volume.yaml: example using persistent storage for web server content.

To deploy the image on a Kubernetes cluster:

1. Review the contents of the template file and edit appropriately for your needs.

2. Apply the YAML template configuration.

   kubectl apply -f nginx-service-deployment-<xxx>.yaml
   

3. Start the service.

   minikube service clear-nginx-service
   

Build and modify:

The Dockerfiles for all Clear Linux* OS based container images are available at https://github.com/clearlinux/dockerfiles. These can be used to build and modify the container images.

1. Clone the clearlinux/dockerfiles repository.

   git clone https://github.com/clearlinux/dockerfiles.git
   

2. Change to the directory of the application:

   cd nginx/
   

3. Build the container image:

   docker build -t clearlinux/nginx .
   

   Refer to the Docker documentation for default build arguments. Additionally:

   • swupd_args - specifies arguments to pass to the Clear Linux* OS software manager. See the swupd man pages for more information.
