Yet another wkhtmltopdf thread

danielslyman · April 5, 2024, 10:18am

I can confirm that printing works when creating a new Print Format using the new builder. Does this consequently mean that all format will need to be recreated?

EDIT:
I just tried sending an invoice via PDF using the new format but receive this error now:

AttributeError: ‘str’ object has no attribute ‘get’

EDIT2:
What is confusing to me is that I used a PWD instance where printing works, running the PWD yaml file leads to the same errors as a supposed production installation.

EDIT3:
If I enter host_name as https://erp.domain.com then I get a timeout error.

It would be fantastic if we could resolve this.

UPDATE:

For anyone struggling with this, for now I got it working like this with the following setup:

Nginx Proxy Manager for TLS termination
ExposePort 8080 on nginx service in Docker Compose file
set “host_name”: “http://10.10.0.111:8080” in site specific config file

I am running Proxmox VE and ERPNext on a VM with Nginx Proxy Manager routing traffic via internal IPs. 10.10.0.111 is the VM IP address. If we could somehow manage to make sure that ERPNext runs behind a separate Nginx Reverse Proxy without people stumbling accross these things I think a lot of people would benefit.

Glad you got it working through this workaround. Sounds to me like a DNS problem though. The wkhtmltopdf binary needs to be able to resolve the site. If it can’t, then you have to fetch the site by IP like you’ve done.

Based on what you shared so far, I’d guess that internal DNS resolution for your site isn’t working for your docker containers. You could determine if that’s the case using a nicolaka/netshoot container connected to your erpnext network. I’d also check to make sure docker is configured to use a DNS server that has an authoritative zone that can give a valid response to DNS A queries for your erpnext site.

Sch-Tim · April 6, 2024, 11:38am

Holy shit now it works here too!

One thought of mine:
Setting a static IP is probably not a good idea in some settings.
If you use docker compose or portainer with stacks the IPs might change after rebuild.

Expose port 8080 on the “frontend” service and set host_name to http://frontend:8080
That way you’re future proof to any IP change.

I should add that I always thought that host_name had to point to the backend service and not the frontend, so I had no chance. But exposing the port was needed here too.

Thanks for the nice collaborative problem solving.

For everyone struggling with this. Here are my compose.yml and env files:
compose.yml
env

Please change the env variables as needed.

Sch-Tim · April 7, 2024, 3:19pm

@danielslyman
I just realized that there is (at least) one caveat with that solution:
When I add things like images to an email, they aren’t shown properly because they are loaded from frontend:8080. Obviously that won’t work.
Probably any other links won’t work too, so that’s a bummer.
Did you find a solution for that?

danielslyman · April 8, 2024, 12:32pm

Hey there,

so for some reason adding https://erp.domain.com into the site specific config file works for me. I removed the DNS entry in /etc/hosts which was seemingly causing the issue. Have you had any progress?

Sch-Tim · April 8, 2024, 7:31pm

I finally made it. I had to make a small change in the docker build files and a few in the compose file.

I forked the frappe_docker git and implemented my changes.
You can find it here: GitHub - Sch-Tim/frappe_docker: Docker images for production and development setups of the Frappe framework and ERPNext

Change:
I updated the nginx resources from the frappe-docker git:
resources/nginx-template.conf

line 10: listen ${NGINX_PORT};
line 11: server_name ${NGINX_SERVER_NAME};

resources/nginx-entrypoint.sh
add

if [[ -z “$NGINX_SERVER_NAME” ]]; then
echo ‘NGINX_SERVER_NAME defaulting to $host’
export NGINX_SERVER_NAME=‘$host’
fi

if [[ -z “$NGINX_PORT” ]]; then
echo ‘NGINX_PORT defaulting to 8080’
export NGINX_PORT=8080
fi

after the other if blocks
and

${TRAEFIK_DOMAIN}
${NGINX_PORT}

into the envsubst string

reason:
I had the problem that nginx produced gateway errors when I redirected erp.domain traffic directly into the frontend container. I tracked the error down to the server_name part in the config. It equals the site name. In my case, it was “frontend”. To uncouple the site name from the domain, I added a second variable.
Additionally, I had to change the listening port to 80 because the default http port is 80. Otherwise, I had to set host_name to erp.domain:8080.
By adding an NGINX_PORT variable, I kept it dynamic.

Change:
Add

hostname: ${TRAEFIK_DOMAIN}

to the frontend service in the compose file
Reason:
One often heard tip is that you should add the frontend container ip to the hosts file.
While this works, it causes two problems:
The first one is that you need root permissions to alter that file.
The second one is that the container IP may change after rebuild.
I realized that docker seems to resolve hostnames internally first. If there is a container with the hostname erp.domain, it goes that way instead of asking the DNS.

Change:
Add

bench set-config -g host_name “http://$TRAEFIK_DOMAIN”;
bench --site frontend set-config host_name “http://$TRAEFIK_DOMAIN”;

as additional config commands to the configurator service in the compose file.

Reason:
The reason should be obvious. You want the backend to explicitly call the internal frontend container. I don’t know what host_name is the default if you don’t set it. But it seems that you need to set it. I chose to set it globally and sitewise to be extra sure.

rmeyer · April 8, 2024, 8:46pm

@revant_one would it make sense to integrate above changes into the official frappe_docker repo?

revant_one · April 9, 2024, 7:12am

Sure, send a PR and make sure tests pass, it’s backward compatible with everything including helm charts, or specify migration guide.

We can completely override the nginx template file by mounting a custom one. No need to do any change to frappe_docker in that case.

Someone else did this trick and used $updated_host instead of $host in custom nginx conf template.

map $host $updated_host {
    default $host;
    "sitehost" erp.example.com;
}

Further you can even change /etc/hosts using extra_hosts for docker or equivalent configuration for other orchestrators.

Sch-Tim · April 9, 2024, 7:58am

Changing frappe_docker directly by including those changes would make it possible to use everything out of the box. You only have to add the specific environment variables.

I know about the extra_hosts parameter but I had the problem that I don’t know what IP the container will get after rebuilding the stack. Do you know how to fetch it instead of hardcoding it?

revant_one · April 11, 2024, 11:33am

Make sure images remain backward compatible for different setups. OR else people will upgrade and need some additional tweaks to get new image working.

May be an entrypoint script? Something like this?

github.com

castlecraft/custom_containers/blob/main/dind-devcontainer/setup-docker-env.sh

#!/bin/bash

DOCKER_IP=$(ping -c 2 docker | awk -F '[()]' '/PING/ { print $2}')
export DOCKER_IP
DOCKER_PORT=2375
export DOCKER_PORT
DOCKER_API="${DOCKER_IP}:${DOCKER_PORT}"
export DOCKER_API

Hyperdata · August 8, 2024, 3:15pm

Hi @danielslyman ,
If set “host_name”: “http://10.10.0.111:8080” in site specific config file then PDF print will working.
But we will facing another issue of Email Notitifcation,coz site_url in Email template will be get from host_name.
So I think set host_name is a IP will not solve a root cause

Hyperdata · August 12, 2024, 6:29am

is this solution work for multi-sites ? How can we define TRAEFIK_DOMAIN align with each site ?

gredso · August 21, 2024, 3:54am

DNS ----> Try running “curl -vI http://web.erp.domain”. Once the domain responds, wkhtmltopdf will work without any issues.

Of course, you need to make sure it’s accessible.

In my case, using a proxy, I edited the /etc/hosts file and, instead of using the local server’s IP, I used the proxy’s IP. That’s it—no other changes needed.

edardev · October 12, 2024, 3:15pm

Hi folks,

I’m experiencing a similar issue, if not the same one, as discussed below: Help Needed: Error with PDF Generation when Sending Email.

I’m unable to send emails using my Gmail account, and I also can’t print invoices. I have already set the host_name to my site name, which is proxied through Nginx Proxy Manager, but the issue persists.

Has anyone found a solution or have any suggestions on what else I might try? Thanks in advance for your help!

revant_one · October 13, 2024, 6:22am

Confirm if the site location is accessible from within workers and gunicorn containers. If the process cannot connect to host_name it’ll not be able to generate pdf.

Access from browser is different, that you already have.

Use extra_hosts or figure out way to resolve images from containers.

edardev · October 13, 2024, 3:43pm

Thank you for your prompt response! I would appreciate your assistance, and I’ll gladly treat you to lunch for your help.

I’m currently running Docker with WSL, Portainer, Nginx Proxy Manager, and a Cloudflare tunnel in a container. The frontend is proxied through Nginx and is accessible via the internet through the Cloudflare tunnel. All containers have external site access, so I don’t need to add extra_hosts directives (which I believe have been deprecated). They are utilizing the Docker bridge network. For example, I’m able to successfully run:

curl https://test.menteware.com

Here’s the stack configuration I have set up in Portainer:

# Status of this document

This document specifies the Compose file format used to define multi-containers applications. Distribution of this document is unlimited.

## Requirements and optional attributes

The Compose specification includes properties designed to target a local [OCI](https://opencontainers.org/) container runtime,
exposing Linux kernel specific configuration options, but also some Windows container specific properties. It is also designed for cloud platform features related to resource placement on a cluster, replicated application distribution, and scalability.

We acknowledge that no Compose implementation is expected to support all attributes, and that support for some properties

Hi @revant_one,

Could you please clarify where I should add the extra_hosts directive? All containers can access external sites and return the expected HTML when I run:

curl https://test.menteware.com

But I’m unsure why I might need extra_hosts in this scenario. Any guidance would be greatly appreciated!

Then image issue need more info. You can exec into the container and do bench --site site.name.com console then try to execute the python functions that are causing problems. Tweak code in console to understand why it triggers error.
