In all cases the containers use the CentOS 7 image, the rest I build myself. I have to figure out why the python container behaves differently. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

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

Zitat von Simon Matter via CentOS : 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. I have this in /etc/profile.d/proxy-config.sh: Hallo, works perfect for wget.

[CentOS] Upgrade CentOS 7.4 to 7.5 and don't want to upgrade it to 7.6
Hi, Is there a way to upgrade from Centos Linux release 7.4.1708 (Core) to Centos Linux release 7.5.1804 (Core) and not up to CentOS Linux release 7.6.1810 (Core) as the product does not support the latest CentOS Linux release 7.6.1810 (Core) version as of now. It is still a work in progress. Any help will be highly appreciable. I look forward to hearing from you. Thanks in Advance.
