Is it expected behavior to have the envs cleared from php-fpm pools, since I see in the php-fpm.conf that the database variables are being set implying that they are being forwarded, but are cleared either way.

i test your stack on a docker swarm cluster behind traefik. before october everything was fine.
new update returns a curl6 error. wordpress admin seems slow using redis

traefik.toml

defaultEntryPoints = ["http", "https"]

[entryPoints]
[entryPoints.http]
address = ":80"
compress = true

Uncomment the following two lines to redirect HTTP to HTTPS.

[entryPoints.http.redirect]
entryPoint = "https"
regex = "^http://localhost/(.*)"
replacement = "http://mydomain.com/$1"
permanent = true

[entryPoints.https]
address = ":443"
[entryPoints.https.tls]
[[entryPoints.https.tls.certificates]]
certFile = "/etc/traefik/certs/mydomain.com.crt"

do you have any plan to add nginx pagespeed support for wordpress using wp super cache plugin??

... which leads to an error

if somebody wanna run this image behind a loadbalancer like traefik 1.7.5 and backed by a swarm cluster:
create a overlay network like below:

docker network create
--driver overlay
--subnet 10.0.9.0/24
--gateway 10.0.9.254
net

deploy traefik following:

docker service create -d --name loadbalancer
--restart-condition any
--replicas 1
--update-delay 2s
--constraint=node.role==manager
--publish 80:80
--publish 443:443
--publish 9090:8080
--mount type=bind,source=/var/run/docker.sock,target=/var/run/docker.sock
--mount type=bind,source=/mnt/efs/traefik/certs,target=/etc/traefik/certs
--mount type=bind,source=/mnt/efs/traefik/traefik.toml,target=/etc/traefik/traefik.toml
--network net
traefik:latest
--docker
--docker.swarmmode
--docker.watch
--web
--loglevel=DEBUG

traefik.toml

defaultEntryPoints = ["http", "https"]

[entryPoints]
[entryPoints.http]
address = ":80"
[entryPoints.http.redirect]
entryPoint = "https"
permanent = true
[entryPoints.https]
address = ":443"
[entryPoints.https.tls]
[[entryPoints.https.tls.certificates]]
certFile = "/etc/traefik/certs/domain.com.crt"
keyFile = "/etc/traefik/certs/domain.com.key"

deploy yobasystems/alpine-php-wordpress under same overlay network "net"
thanks dominic create this wonderful image
everything very modular and beginner friendly
with this base image you can handle 100-150 concurrent user
with pagespeed, varnish, wp supercache (8000-8500) concurrent in a single EC2
working on it
i will publish a optimized image based on this image using pagespeed,varnish,wp supercache

add following (nginx specified) top of the wp-config:

define('FORCE_SSL_ADMIN', true);
if (strpos($_SERVER['HTTP_X_FORWARDED_PROTO'], 'https') !== false)
$_SERVER['HTTPS']='on';

otherwise your site will be loaded without style css and js

PS:
can i just install varnish 5 using:
apk add varnish
can i add:
varnishd -f /etc/varnish/default.vcl -s malloc,64M -a 0.0.0.0:80

to /run.sh

expecting:
varnish,nginx, php-fpm will boot upon container startup based on your infra??

to do:
add wp supercache with pagespeed (working on it)
Thanks

Curl is installed twice on the same command

i am running behinf traefik. iedit wp-config.php as you guys said running ubuntu 18.04
docker swarm.
after deploy your stack i got

Unable to reach WordPress.org at wordpress.org: cURL error 6: Could not resolve host: wordpress.org

what is the correct user ID and group ID I should use?

I tried this one:
The following user and group id are used, the files should be set to this: User ID: Group ID:

chown -R 100:101 /data/{domain}/html

E.G

chown -R 100:101 /data/yobasystems/html

it returned directory index of "/usr/html/" is forbidden.

then I tried set to my user ID which created the folder. failed as well.

using this git:
https://github.com/codecasts/php-alpine

or is there any way to update the php to the latest one or update nginx to mainline ??
