Letsencrypt for WordPress in a docker image

Modded official Wordpress docker image with ability to run letsencrypt

This repo is the source for the docker hub image https://hub.docker.com/r/vitr/letsencrypt-wordpress/

You may use this image for quick obtaining certificates from https://letsencrypt.org/ and use them somewhere else or incorporate these ideas into your production images. I haven't changed much, just added these two features:

• ability to restart apache, otherwise the container stops everytime letsencrypt tries to restart apache, note the tail command in apache/docker-entrypoint.sh
• preinstall letsencrypt client, note # install letsencrypt section in apache/Dockerfile

how to build image

git clone https://github.com/vitr/docker-letsencrypt-wordpress.git
cd docker-letsencrypt-wordpress/apache
docker build -t vitr/letsencrypt-wordpress .

or you can use my pre-built image from the docker hub https://hub.docker.com/r/vitr/letsencrypt-wordpress/

how to run letsencrypt

copy docker-compose.yml from this repo into wp folder in your homedir (~) (the reason for this is that docker compose requires absolute paths for volumes, e.g. ~/wp/letsencrypt). Then run the compose

docker-compose up -d
docker exec -ti wp_wordpress_1 bash

now run inside the wordpress container

cd /opt/letsencrypt
./letsencrypt-auto --apache -d yourdomain.com -m youremail@domain.com --agree-tos --redirect

You may also try dry-run to test your system before issuing a real certificate (I messed up with containers a lot and hit their rate limit 5 certs in 7 days)

./letsencrypt-auto certonly --dry-run --apache -d yourdomain.com -m youremail@domain.com --agree-tos --redirect

the certificate files will be stotred in ~/wp/letsencrypt/live/yourdomain.com and you can reinstall with

./letsencrypt-auto install --apache -d yourdomain.com -m youremail@domain.com --agree-tos --redirect \
--cert-path /etc/letsencrypt/live/yourdomain.com/cert.pem \
--key-path /etc/letsencrypt/live/yourdomain.com/privkey.pem \
--fullchain-path /etc/letsencrypt/live/yourdomain.com/fullchain.pem 

@TODO: add auto renewal

@TODO test with fpm

set correct locale

apt-get install locales
locale-gen "en_US.UTF-8"
localedef -v -c -i en_US -f UTF-8 en_US.UTF-8
export LC_ALL="en_US.UTF-8"
export NCURSES_NO_UTF8_ACS=1

./letsencrypt-auto --help all

-n, --non-interactive, --noninteractive Run without ever asking for user input. This may require additional command line flags; the client will try to explain which ones are required if it finds one missing (default: False)
