Currently MSA and appliances do not have proxy settings available for configuring through UI / deploy options.
Also all stateless appliances cannot use permanent proxy settings.
However, if MSA needs to reach out to MMS through proxy, the following workaround can be performed:
in JetDR 4.x MSA edit file /etc/init.d/vme2:
...
CATALINA_OPTS_MEM="-server -Xms3g -Xmx3g"
current_date=`date +%s`
CATALINA_OPTS_DUMP="-XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath='/tmp/jetdr-${current_date}.hprof'"
CATALINA_OPTS_EXTRA="-Djava.awt.headless=true -Djava.security.egd=file:///dev/urandom -Djavax.xml.bind.context.factory=com.sun.xml.internal.bind.v2.ContextFactory"
CATALINA_OPTS_PROXY='-Dhttps.proxyHost=<proxy ip/fqdn> -Dhttps.proxyPort=<proxy port> -Dhttp.nonProxyHosts="localhost|127.0.0.1|<local subnet(s)>"'
[ -z "$CATALINA_OPTS" ] && CATALINA_OPTS="$CATALINA_OPTS_MEM $CATALINA_OPTS_DUMP $CATALINA_OPTS_EXTRA $CATALINA_OPTS_PROXY"
export JRE_HOME CATALINA_OPTS
...
added line 7 and reference to CATALINA_OPTS_PROXY on line 9.
local subnets have to be mentioned in wildcard format (e.g. 10.*.*.*; ref.: https://docs.oracle.com/javase/8/docs/technotes/guides/net/proxies.html)
After the change, vme2 service must be restarted for the options to be applied.
in JetDR 5.0 and later MSA, similar change should be done in file /etc/tomcat/conf.d/fio.conf, and msa-tomcat service restarted.
The issue to track more user-friendly proxy setting process is DRBC-7794 - Getting issue details... STATUS
