Issues when installing Besu nodes behind proxy environment

[eum602]

When nodes are behind http proxy it is necessary to add previous steps to deal with that issue:
Configuring environment variables:

export HTTPS_PROXY="http://YOUR_PROXY_HOST:YOUR_PROXY_PORT"
export HTTP_PROXY="http://YOUR_PROXY_HOST:YOUR_PROXY_PORT"
export http_proxy="http://YOUR_PROXY_HOST:YOUR_PROXY_PORT"
export https_proxy="http://YOUR_PROXY_HOST:YOUR_PROXY_PORT"

export _JAVA_OPTIONS='-Dhttp.proxyHost=YOUR_PROXY_HOST -Dhttp.proxyPort=YOUR_PROXY_PORT -Dhttps.proxyHost=YOUR_PROXY_HOST -Dhttps.proxyPort=YOUR_PROXY_PORT'

If ansible has failed throwing docker issues then try to do this:

mkdir -p /etc/systemd/system/docker.service.d
#Create a http-proxy.conf file and add the following:
vi /etc/systemd/system/docker.service.d/http-proxy.conf
***
[Service]
Environment="HTTP_PROXY=http://192.168.56.85:3128"
***
#Similar with this file:
vi /etc/systemd/system/docker.service.d/https-proxy.conf
**
[Service]
Environment="HTTPS_PROXY=http://192.168.56.85:3128"
**

#Finally reload daemon and restart docker service:
systemctl daemon-reload
systemctl restart docker

In order to verify that docker environment variables where correctly configured run this:
systemctl show --property=Environment docker
