[adobejmong]

What changed?

Major Changes

• Add new base from Ubuntu 20.04 (docker-base:5.0.1-ubuntu-20.04) to Ubuntu 22.04 (docker-base:5.1.0-ubuntu-22.04). Will eventually make this the default
• Removed previous nginx installation from ppa:ondrej/nginx and software-properties-common
• Removed curl, gnupg2 if installed
• Added new install nginx script scripts/install_nginx.sh, from standard nginx install: http://nginx.org/en/linux_packages.html#Ubuntu
• Added new install njs module script scripts/install_njs.sh to install nginx-module-njs module. See ETHOS-36876 @kmashint - https://nginx.org/en/docs/njs/
• Added new cleanup script scripts/cleanup.sh to purge unnecessary packages in final image
• Added SERVER_ENABLE_NGX_HTTP_JS. If set to true, it will enable i.e. load_module the nginx njs module
• Updated Ubuntu Dockerfile to use multi-stage builds

Bug Fixes

• Fix duplicate extension warning due to grep -x not matching any previous entries. Sample error

  nginx: [warn] duplicate extension "woff", content type: "font/woff", previous content type: "font/woff" in /etc/nginx/mime.types:100
  nginx: [warn] duplicate extension "woff2", content type: "font/woff2", previous content type: "font/woff2" in /etc/nginx/mime.types:101

Doc Changes

• Add deprecated messages to Alpine, CentOS
• Move most of the docs to docs/
• Add additional output in docs/ when testing HTTPS usage locally
• Add quickstart
• Add troubleshooting

CI Changes

Nginx Package Versions

As of Jul 15, 2022, these are the versions that it builds with:

ii  nginx                       1.22.0-1~jammy                          amd64        high performance web server
ii  nginx-module-njs            1.22.0+0.7.5-1~jammy                    amd64        nginx njs dynamic modules

Steps to build locally

1. Clone fork

cd /tmp
git clone git@github.com:adobejmong/docker-nginx.git
cd docker-nginx
git checkout ETHOS-36876

2. Build it locally

# Builds an AMD64 image
make

# To build an ARM64 image
VERSION=arm64 PLATFORM=linux/arm64 make

Steps to test locally

To test the njs module, I worked with @kmashint to create a simple test. The test assumes that you have dgoss installed.

cd tests/njs
make dgoss

Sample output:

GOSS_WAIT_OPTS="-r 60s -s 5s > /dev/null" dgoss run -e SERVER_ENABLE_NGX_HTTP_JS=true -p 8080:8080 docker-nginx:njs-test

Image Size comparison

Use docker images or docker inspect for the linux/amd64 architecture:

Image	Size (in MB)
Original (docker-nginx:10.0.0)	115
