NAME¶
kanif.conf - configuration file for kanif
SYNOPSIS¶
$HOME/.kanif.conf,
/etc/kanif.conf or
/etc/c3.conf
DESCRIPTION¶
kanif.conf is the configuration file for
kanif. It is optional and
only helps the management of static clusters (configurations that do not
change much over time). It mimics the syntax of C3 configuration file.
It is composed of a sequence of one or more cluster definitions. Each cluster
definition is made of the word "cluster" followed by the cluster
name and, enclosed in a pair of curly braces :
- •
- the front node specification. This is either:
- •
- a simple hostname which can be reached from the inside of
the cluster (compute nodes).
- •
- two names separated by a colon. The first name is the name
used from the outside to log on the front node (not used by kanif).
The second is the name used from the cluster compute nodes to reach the
front node.
- •
- an hostname with a colon prepended. This is used for
indirect clusters. These are not supported by kanif at this
time.
- •
- zero or more compute nodes specifications:
- •
- a simple hostname (anything that is not of the following
form)
- •
- an host set made of a prefix, a range and a suffix.
- •
- an exclude directive that must follow an host set or
another exclude directive. This is made of the word "exclude"
followed on the same line by either a single number or an interval between
brackets. This applies to the range of the preceding host set. If the
exclusion is an interval, the separator between the word
"exclude" and this exclusion is optional.
- •
- a dead node. The word "dead" followed by the name
of the dead node on the same line.
Notice that all nodes excluded (using exclude directives or dead nodes) will not
take part of the deployment, but are still taken into account in cluster
ranges when giving machines specifications to
kanif (they are kind of
placeholders). This is the interest of specifying nodes as dead or excluded
rather than dropping them from the definitions.
EXAMPLE¶
cluster megacluster { # The # character introduce comments
megacluster-dev
megacluster0[1-9]
megacluster[10-64]
}
cluster supercluster {
super-ext:super-int
exclude # The host "exclude"
super[01-99]
exclude 02 # "super02" is excluded
exclude[90-95] # "super90" to "super95" are excluded
dead # The host "dead"
dead othernode # "othernode" is dead
}
