Why do you use 2 different cache plugins? It will not be too much to add varnish in front?
No, I have five websites, 3 uses w3Total Cache and 3 uses Super cache.
Please do you have guide on how to set up varnish on plesk for this plugin?
For this plugin no, but if you want to setup varnish on plesk, you have just to follow the official documentation : https://www.varnish-software.com/wiki/content/tutorials/wordpress/index.html
Also, My website are using “FPM application served by Apache” and FASTCGI
This is not mention in this article
First Thanks for this nice Solution. But if i am using https:// it just says to many Redirects.
Hi,

anyone using it on cloudlinux 7.3 with a production wordpress site?
Hello;
You did not mention how we are to add the varnish to docker, i have about 15 here from search
also is it possible to implement this server wide for PHP sites?
Is there no moderator? really disappointed
I am having the below error.
Error: {“message”:”driver failed programming external connectivity on endpoint varnish (4bb8f14f3b3666a64871981347350a65b75dd38c1c482bf1a95229aaab3f7ad3): (iptables failed: iptables –wait -t filter -A DOCKER ! -i docker0 -o docker0 -p tcp -d 172.17.0.2 –dport 80 -j ACCEPT: iptables: No chain/target/match by that name.n (exit status 1))”}
Hello
I followed the configuration but i still have a MISS and bind(): Cannot assign requested address
I checked and the port 7080 is well the port for plesk. Mod security is deactivated for this website.
Thanks in advance

You can ignore the bind notification. It seems to be because the docker image has no inet6 local address and varnish tries to bind on all interfaces.
I added an explanation here: https://talk.plesk.com/threads/bind-cannot-assign-requested-address-error-log-while-using-varnish-for-wordpress-in-a-docker.343321/#post-839437
there is no /etc/varnish/default.vcl here
Everything seems to work fine, except for the fact that I can’t seem to purge posts from wordpress. The connection from the domain to Varnish is refused.
If i run: curl -x purge [domain], I get: Failed connect to purge:1080; Connection refused.
Also some ‘purge plugins’ can’t seem to connect. I already tried to add: “0.0.0.0” to the ACL list.
you have varnish in /etc directory?
Yes. I do… I think it’s an ACL thing. But not sure.
i can’t find varnish in /etc/
You need to open the container with the exec command.
how do i do that?
@jaap_veenstra:disqus how did you do it?
Its all in the tutorial. Just follow the steps.
i just did but its not caching… showing red.
I’m not An engineer. There are tons of variables. Take a look at your IP tables config. There was An error there?
NO /etc/varnish/default.vcl
Is know. But there is an ACL rule in the default.vcl.
I followed the complete guide. Varnish is working, except for purging.
Please, I can not install wordpress. Is giving the following error.
Erro: O seguinte erro ocorreu durante o download do aplicativo: ODBC error #42S02: [MySQL][ODBC 5.1 Driver][mysqld-5.1.73]Table ‘apsc.aps_package’ doesn’t exist
works on non ssl and not working on ssl i get too many redirects..
I second what Jaap is saying, with some thinkering but closely following the instructions all kind of WordPress setups will work fine with this Varnish Docker setup. Purging on the other hand is something I am looking into aswell as whatever I do that does not seems to take.
If there is suggestion on getting that working … please I am all ears 😉
This article seems to not be complete as it is missing the detail of how to actually edit the file in the docker contatiner, as it contains no txt editor and you can’t seem to install one, so how do you actually change the port.
Robin, the vi editor is available in the docker image. But you can also just install your own preferred image by running: yum install
But my advise is to use volume mapping to map the file to a file outside your docker image so any changes you make to the file will not be lost if you re-recreate the image. Doing so will erase any changes made inside the image.
Works on non ssl and not working on ssl i get too many redirects..
How we can resolve this issue ?
i’m using wordpress
Same issue here: Works on non ssl and not working on ssl i get too many redirects..
Followed exactly multiple times, and getting the same issues:
– HTTPS site visit looks strange via Varnish – while HTTP is okay.
– HTTPS access to wp-admin gives “too many redirects” error, changing wp-admin to http works okay (but its a security issue).
– I can not restart the docker container as soon as the redirect rule for the domain is in place and default.vcl is edited. Error:
Could not create _.vsm.1: File exists
Happens with centos-release-7-4.1708.el7.centos.x86_64 / Plesk 17.5.3 U#39
Great post, helped me out alot!
I had to open port 7080 in Plesk for Varnish to be able to contact my backend.
How solve this error ?
Erro: {“message”:”driver failed programming external connectivity on endpoint varnish (a2301cf3dd3ada07f83fe84fe5009eae90afcc9fb9e5a18831060181a32e25d3): (iptables failed: iptables –wait -t filter -A DOCKER ! -i docker0 -o docker0 -p tcp -d 172.17.0.2 –dport 80 -j ACCEPT: iptables: No chain/target/match by that name.n (exit status 1))”}
Everything ok until I changed from http to https. That “It also works and the best part of it is that you don’t have to change anything!” Is NOT true at all.
Everybody with the same error would be nice an explanation on how to do it.
It works perfectly fine with WordPress and HTTPS! You can check a WordPress demo page with the Varnish integration with activated SSL (Let’s Encrypt certificate) here: https://wordpress-varnish.code-sprint.de/
Here is a screenshot with the Header response: https://www.plesk.com/wp-content/uploads/2018/03/varnish-wordpress-docker.png
What did I do? I just followed my own instruction step-by-step from this article. You only get a redirect issue if you don’t disable the “Permanent SEO-safe 301 redirect from HTTP to HTTPS” option or maybe use strange rules in your .htaccess (only encountered this issue with the option mentioned above).
Regarding the purging process: Easiest thing is to restart the Docker container (from Plesk UI or command line) or sending a PURGE cURL request ($ curl -X PURGE example.com). See manual for more information!
Hi,
your test website https://wordpress-varnish.code-sprint.de/ not working proper…
Also I have problems with the loop with the HTTPS protocol following your tutorial.
Is the problem in the latest version of Onyx?
This tutorial misses something for https to work. Http works fine. Would be nice if you find what is it and tell us
If with 301 redirect is not working how you deal with both http an https sites working? Google will mark your site with duplicate content.
The redirect from HTTP to HTTPS works in this constellation (but without a 301 code). If you check my demo website, then you will see that it is also possible to redirect with a 301 code:
https://www.plesk.com/wp-content/uploads/2018/03/wordpress-varnish-docker-301-redirect.png
Though, this requires some changes in the nginx.conf and default.vcl files. Since the nginx.conf is created automatically, this can be seen only as a workaround. I can share the solution if somebody is interested in it! 🙂
Yes! I am interested. My testing site pcbxxi.com is working with varnish but both http and https are valid. I don’t want http just https.
Hello.
I have problems to make works in https. I try with the plugin Really Simple SSL but I can’t make to put working. I leave WordPress with http in site URL and WordPress URL. I try it to make the redirection with nginx but didn’t work for me. Can tou share the solution with redirection 301 please.
Thanks.
When I use varnish on HTTP, x-cache = HIT, but with HTTPS, x-cache = MISS.
Followed your instructions, followed every other instruction I could find on Google, nothing seem to work. I would much apreciate if you could post all full step-by-step instruction to enable varnish on HTTPS.
Thank you in advance.
Is varnish that good to loose this time we are loosing on trying to get https working?
I followed the instructions exactly and it does not work. I can not connect to Apache.
I get the following error message:
Error 503 Backend fetch failed
Backend fetch failed
I have the default.vcl with server ip and port 7080 adapted and it does not work.

The correct:

it is possible to have support for a woocommerce configuration?
I’ve tried to follow this step and add code but doesn’t work:
https://docs.woocommerce.com/document/configuring-caching-plugins/
https://wordpress.org/support/topic/varnish-configuration-not-working-in-woocommerce/
Hello, I still have the error 503! I opened putty, I got the ID I make the other order and nothing happens!
docker exec -it xxxxxxxxx bash
nothing is happening.
Unable to edit the file /etc/varnish/default.vcl
For those who can’t find the file, /etc/varnish/default.vcl you are missing this step:
“Copy the Docker ID and use the following command to access the Docker container
$ docker exec -it ID bash // Replace ID with the correct container ID”
Once inside the container, use VI or install Nano (yum install nano) to edit the VCL file
Thanks Chris!
Give me the full command to create and edit vcl files.
One thing this tutorial doesn’t explain is, It will NOT work with Plesk Firewall enabled.
Sure it does, you just need to create a filter opening the ports it uses
Hi all,
in my case i have this error from varnishlog:
BACKEND_FETCH
backend boot.default: fail errno 111 (Connection refused)
Is a problem of NGINX or something wrong on default.vcl
Thanks
Hey Luca,
Best raise a ticket for our support to look into it: https://support.plesk.com/hc/en-us
Thanks
I just successfully installed it for a Magento 2 site.
You must disabled “Permanent SEO-safe 301 redirect from HTTP to HTTPS” in Hosting Settings.
And configure 172.17.0.2 incoming TCP 7080 in the PLESK firewall !
If you use ModSecurity you must deactivate a rule (with help log)
i am getting too many redorects witha magento 2 website.
port 7080 incoming is accepted and Permanent SEO-safe 301 redirect from HTTP to HTTPS diasbled.
iptables -nL | grep 7080
ACCEPT tcp — 172.17.0.0/16 0.0.0.0/0 tcp dpt:7080
ACCEPT tcp — 172.17.0.2 0.0.0.0/0 tcp dpt:7080
ACCEPT tcp — 0.0.0.0/0 0.0.0.0/0 tcp dpt:7080
I cannot get this method working for me because I am NOT using Nginx as a proxy but rather as a full frontline server. What should I do?
In order to have curl -X PURGE domain.com to work. 2 things needed to be done from my end.
1. add the domain on the server /etc/hosts
server_IP domain.com
2. When check on the server ifconfig , should got 1 docker0 network with IP 172.17.0.1 ( I guess all server should have this same IP ) . On the Varnish docker , add this IP onto acl purge portion.
=====
# SET THE ALLOWED IP OF PURGE REQUESTS
# ##########################################################
acl purge {
“localhost”;
“127.0.0.1”;
“172.17.0.1”;
}
======
save the settings and restart the Varnish docker container.
Once done ,
======
[[email protected] ~]# curl -X PURGE domain.com
