CentOS - Jan 2019 - how to set proxy systemwide (wget and docker)

Hallo,
what is the right way to set a proxy systemwide using centos 7?
I need this for wget and docker. 
My first idea was /etc/environment but allthough the proxy is set wget and
docker don? t connect to their target-systems.

Thanks for hints

Ralf

How are you doing it in /etc/environment? And how is the process
calling wget and docker getting initiated? The data in
/etc/environment should be set if the process is in a PAM aware
environment, but I would expect that there may be ways where you could
not get it set. The other place to put it would be in
/etc/profile.d/proxy.sh and /etc/profile.d/proxy.<fill in here> but
that would require also the shells sourcing those files not to clear
out their environment variables or to make sure they  source
/etc/profile.d when starting up.

I have this in /etc/profile.d/proxy-config.sh:
-----%<---------------------------------
PROXYHOST="proxy"
PROXYPORT="8080"

for CFGFILE in /etc/sysconfig/proxy-config ${HOME}/.proxy-config; do
  [ -s $CFGFILE ] && . $CFGFILE
done

export http_proxy="http://${PROXYHOST}:${PROXYPORT}"
export HTTP_PROXY="http://${PROXYHOST}:${PROXYPORT}"
export https_proxy="http://${PROXYHOST}:${PROXYPORT}"
export HTTPS_PROXY="http://${PROXYHOST}:${PROXYPORT}"
export ftp_proxy="http://${PROXYHOST}:${PROXYPORT}"
export FTP_PROXY="http://${PROXYHOST}:${PROXYPORT}"
export all_proxy="http://${PROXYHOST}:${PROXYPORT}"
export ALL_PROXY="http://${PROXYHOST}:${PROXYPORT}"
export no_proxy="localhost,$(hostname -s),$(hostname -f),$(hostname
-d),127.0.0.1"
export NO_PROXY="localhost,$(hostname -s),$(hostname -f),$(hostname
-d),127.0.0.1"
export RSYNC_PROXY="${PROXYHOST}:${PROXYPORT}"

unset PROXYHOST PROXYPORT CFGFILE
-----%<---------------------------------

Hallo,
works perfect for wget.
Docker fails
[root at srvdockerndxx tmp]# docker run --rm --privileged -v

Seems as if docker needs more or other proxy-configurations.

Hallo,
