Debian container node setup
This page is here to document what I'm doing on Sirius. This will eventually become a Salt state/Puppet manifest/Ansible playbook/whatever it is that we use now.
- Debian can be installed by using the "debian" boot option from PXE, make sure you first remove eth0 from any port groups on the switch
apt-get install ifenslave
auto lo iface lo inet loopback auto bond0 iface bond0 inet static address 220.127.116.11 netmask 255.255.254.0 gateway 18.104.22.168 network 22.214.171.124 slaves eth0 eth1 bond-mode 802.3ad bond-miimon 100 bond-downdelay 200 bond-updelay 200 dns-nameservers 126.96.36.199 188.8.131.52 dns-search csl.tjhsst.edu
ifdown eth0 ifdown eth1 ifup bond0 service networking restart
On the switch (for Sirius specifically, pick the correct things):
conf t inter Po4 switchport mode access switchport access vlan 1600 no shutdown inter Gi1/0/12 switchport mode access switchport access vlan 1600 port-channel 4 inter Gi1/0/13 switchport mode access switchport access vlan 1600 port-channel 4 exit exit wr mem exit
switchport mode trunk is not something we want, because I'm too lazy to set it up.
Next you'll want to set up storage. Storage is currently exported with NFS from Bottom at
/storage/export. You may need to edit
/etc/exports on bottom to allow a new host to connect. Once you've done that, add a line like
bottom:/storage/export /lxc/containers nfs rsize=8192,wsize=8192,timeo=14 to
/etc/fstab. Then make an appropriate symlink:
ln -s /lxc/containers/ /var/lib/lxc.
Each container server has a private IPv4 network for the containers on it, which is NATted to the server's external IP. Every container has an IPv6 address which is used to access it from off of the server. An instance proxy listening on i.e. *.container.csl.tjhsst.edu can be configured to proxy HTTP(s) requests to IPv6 container addresses.
