.SH NAME
\f3pcp-kube-pods\f1 \- list Kubernetes pods to scan for running PCP services
.SH SYNOPSIS
\f3$PCP_BINADM_DIR/discover/pcp-kube-pods\f1
.SH DESCRIPTION
.B pcp-kube-pods
uses
.BR kubectl (1)
to provide a list of IP addresses for PODs running in a local
Kubenetes cluster, that may be running PCP services like
.BR pmcd (1)
and
.BR pmproxy (1).
.PP
It is used by the
.BR pmfind (1)
command and the
.BR pmDiscoverServices (3)
API as a ``shell'' command.
.PP
The script invokes the
.B "kubectl get pod"
command line (see
.BR kubectl-get (1))
to discover IP addresses for pods.
The
.B .status.podIP
output field is extracted from the Kubernetes pod object(s).
Additional options can be specified via configuration file,
such as
.I "-l service=database"
to restrict the results using Kubernetes pod labels.
The default configuration file is
.BR $PCP_SYSCONF_DIR/discover/pcp-kube-pods.conf .
.PP
If no local
.B kubectl
command is found, nothing is reported and an exit code
indicating success is returned.
.SH DIAGNOSTICS
All diagnostics produced are provided by the
.B kubectl
command.
.P
The
.BR kubectl
exit status is propogated unchanged.
.SH FILES
.TP 5
.I $PCP_BINADM_DIR/discover
default path to address discovery commands like
.B pcp-kube-pods
.TP
.I $PCP_SYSCONF_DIR/discover/pcp-kube-pods.conf
configuration file containing command line options passed to
.B kubectl-get
.TP
.I $PCP_SYSCONF_DIR/discover/pcp-kube-pods.disabled
existence of this file causes the script to report nothing
.SH PCP ENVIRONMENT
Environment variables with the prefix \fBPCP_\fP are used to parameterize
the file and directory names used by PCP.
On each installation, the
file \fI/etc/pcp.conf\fP contains the local values for these variables.
The \fB$PCP_CONF\fP variable may be used to specify an alternative
configuration file, as described in \fBpcp.conf\fP(5).
