Dear, I have an issue about hide processes on the host
I have a watchdog script on the host that ensure slapd is up there is different behavior using pidof or pgrep the ps aux output # ps aux|grep slapd root 2444 0.0 0.2 149296 6816 ? Ssl May03 1:21 /usr/sbin/slapd -4 -u root -g root -f /etc/ldap/slapd.conf -h ldap://127.0.0.1:389/ root 23279 0.0 0.1 29040 6176 ? Ssl 23:40 0:00 /usr/sbin/slapd -4 -u root -g root -f /etc/openldap/slapd.conf -h ldap://127.0.0.1:389/ Has we can see: The process 23279 running inside the container the pgrep output the same output # pgrep -l -f "/usr/sbin/slapd" 2444 /usr/sbin/slapd -4 -u root -g root -f /etc/ldap/slapd.conf -h ldap://127.0.0.1:389/ 23279 /usr/sbin/slapd -4 -u root -g root -f /etc/openldap/slapd.conf -h ldap://127.0.0.1:389 Only the pidof point to the right process # pidof /usr/sbin/slapd 2444 The problem is when the slapd process on the host is down, my script detect the container process, it think that slpad is up and did not react. I have searched if there is some "pointers" on the host inside the /proc/xxx directory (eg /proc/status, /proc/cmdline ) that shgould helps my script to detecting that the process is not a "host" process but no luck. the only way is to do function that parse the result of #lxc-ps --lxc aux|grep ldap detect/return the slapd pid to the main script in order to force it to bypassing this pid in the detection method. But using this kind of solution is heavy when there is several containers running on the same host and when you need to do the same task with apache or mysql or any softwares that running many child (postfix, amavisd-new,squid...) I have read some post on the mailing list that there is no currently solutions to fix this situation with LXC. Is there a way hiding containers processes without LXC help ? ------------------------------------------------------------------------------ WhatsUp Gold - Download Free Network Management Software The most intuitive, comprehensive, and cost-effective network management toolset available today.
