Checklist

• [yes] issues already, but found no answer/solution
• [yes] I checked the documentation and wiki, but found no answer/solution
• [yes] I am running the latest version and the issue still occurs
• [no] I am sure that this issue is about SteVe (and not about the charging station software or something unrelated to SteVe)

Specifications

SteVe Version     : Steve-3.4.9 docker container
Operating system  : Ubuntu 20.04 
JDK               : maven:3.6.1-jdk-11
Database          : mariadb:10.4

Expected Behavior

Docker application starts with in about 2-5 minutes

How the logs usually look

Actual Behavior

Docker application starts with in about 60-90 minutes

When I look at the logs I notice that when I start Steve I run into an error that ends after 60-90 minutes with a timeout and then he starts the server successfully.

I assume that it is related to the following log or short-circuited command: org.hibernate.validator.internal.util.Version (main) - HV000001: Hibernate Validator 6.1.7.Final

What the logs look like with the error: after 60-90 minutes

Steps to Reproduce the Problem

1. Server behind a proxy server with certificate type
2. Configure Steve and server as specified
3. start steve with docker-compose up

Additional context

Modifications due to proxy server

1. Modifications to server /etc/environment
   
2. Improving the proxy certificate /usr/local/share/ca-certificates/ca.crt
3. Adaptations to Docker for pull and push nano /etc/systemd/system/docker.service.d/http-proxy.conf
4. Adaptations to Docker so that Conatainer can use wget .docker/config.json + Certificate import
5. Adaptation to Conatiner image so that I can use mvn /usr/share/maven/conf/settings.xml

the logfiles arent readable. Is there a reason you want to use docker and a proxy? It makes the setup a lot more complicated.

dont forget you need to proxy a websocket connection in both directions for ocpp-j

Hi, The problem is that I need the proxy to access the Internet. As far as I understand, not using Docker would not change anything. Since the problem is when starting the Steve app. Downloading the app works.

What exactly do you mean by „need to proxy a websocket connection in both directions for ocpp-j”

My understanding is that I only need the proxy to download the Steve app. Since Steve and the Charge Point are on the same network and both are already communicating with each other. Without going through the proxy server as it is only needed for an Internet connection.

The Dockerfile in this repo has a number of problems. Doing the entire build in the "run" stage is not a good pattern.

You're welcome to try the Dockerfile I made for Steve:

https://github.com/keeth/steve/blob/hv/Dockerfile

It uses a multi-stage build so that only the jar is copied to the final image. I build it like this:

docker build -t keeth/steve --network=host .

The --network=host bit is because the build requires a connection to a mariadb instance that has been initialized with the Steve SQL. Also I added 127.0.0.1 mariadb to /etc/hosts on my laptop so that the mariadb hostname would resolve.

Hope this helps!
