Question Docker: Informations / How it works?

[omexlu]

Hello,

I want to install the extension "docker" on my "Plesk Onyx" installation.

In this "docker" i want to install "Zammed" (https://docs.zammad.org/en/latest/install-docker-compose.html)

Now my Questions are:
- I have a domain point to the server (subscription allready setted) => srv.domain.tld
QUESTION: So here the container will be avaible @ https://srv.domain.tld:PORT (PORT FROM CONTAINER)
- https://docs.zammad.org/en/latest/i...ml#setting-vm-max-map-count-for-elasticsearch
QUESTION: These settings must be done at the container right?

How easy it is to install that in there?:
https://docs.zammad.org/en/latest/install-docker-compose.html

Thanks

Hi,

I have testet it with the package mention above.

Runned that on host:

• sysctl -w vm.max_map_count=262144

But i get the error in docker vm.max_map_count : Read-only filesystem

What can i do there ? reboot dont help

Hi omexlu,

change at "/etc/sysctl.conf" the setting for "vm.max_map_count" to "262144" ( which is mostly setup to "65530" ). After a reboot, you can check the setting with the command ( logged in as user "root" ) :

sysctl vm.max_map_count

Thank you i will give a try , i can break nothing with that setting?

I never would suggest something, that could harm your server - you just change some "standart" - linux settings here!

sysctl vm.max_map_count
vm.max_map_count = 262144

And in Container i got always this error:
sysctl: setting key "vm.max_map_count": Read-only file system

And it dosen't run "zammed" i don't understand it.

Hi omexlu,

you might have noticed, that this forum is a "plesk-related" community and your described issue is the result of a third-party component - usage. I assume, that you would like to use "Elasticsearch" in combination with your "zammad" - docker - installation, so pls. consider to ask depending issue(s)/error(s)/problems at: => https://discuss.elastic.co/

The Guys from there think that plesk is not compatible with docker-compose?

Hi omexlu,

just a shoot out of the blue: Did you actually INSTALL "docker-compose" on your server? ( hint: Pls. use the command line as user "root" and type: docker-compose -v )

Hi,

No i don't have installed it (docker-compose) but as plesk support says me it is not supported by plesk, so i suppose installing it on the server change nothing, because plesk can't handel that on panel?

Could you pls. name the supporter, who told you, that "docker-compose" is not supported?


Apart from that, you want to install the zammad version "zammad-docker-compose" and you don't have "docker-compose" installed on your server, which is pretty weird from my point of view - you should be aware, that dependencies will always conflict here.
I just tested the docker installation ( WITH docker-compose installed! ) and I had no problem in installing all depending images for a testing - subdomain. I didn't get all services to run, because I was too lazy to configure all the needed ports, so the nginx-container didn't start for example, but I had no problem at all, installing all the seven containers.

Hi,

I don't want to deface somebody but here the mail:

Docker-compose is not supported. You can try to implement it manually.

Let us know in case of any questions.

Alexandra Tyutyunnikova

So its mentioned that i can install it manually

How have you make it:
- Install 'docker-compose'
- Than installed the 'zammad-docker-compose' from Plesk panel?

About the Ports, i need only to configure nginx as exposed ports because nginx handle the rest in the container.

Thanks

Hi omexlu,

well, the answer just indicates, that Plesk didn't integrate "docker-compose" (yet) into Plesk Onyx yet, I suppose, because the additional note points to a manual installation. You might consider to post this a feature request at: => http://plesk.uservoice.com/


Installation description for "docker-compose": => https://github.com/docker/compose/releases


Actually, you should use the standart way, when working with docker-compose:

Implement the needed git into your (sub)domain, where you choose for example the local folder "/var/www/vhosts/YOUR-DOMAIN.COM/test-zammad.YOUR-DOMAIN.COM/" for the automatic deployment. Afterwards, you login over ssh and move to the git - folder and start the installation process. Example:

cd /var/www/vhosts/YOUR-DOMAIN.COM/test-zammad.YOUR-DOMAIN.COM
docker-compose up
​

Afterwards, you have all the 7 zammad-docker-compose container, which settings you may now edit over the Plesk Control Panel. ​

Thanks for you reply. I will give this a try on a local machine this evening
So afterwards i can setting the ports on plesk

Thank you.
