openshift.ks

# This script configures a host system with OpenShift components.
# It may be used either as a RHEL6 kickstart script, or the %post section may be
# extracted and run directly to install on top of an installed RHEL6 image.

# SPECIFYING PARAMETERS
#
# If you supply no parameters, all components are installed with default configuration,
# which should give you a running demo.
#
# For a kickstart, you can supply further kernel parameters (in addition to the ks=location itself).
#  e.g. virt-install ... -x "ks=http://.../openshift.ks domain=example.com"
#
# As a bash script, just add the parameters as bash variables at the top of the script (or environment variables).
# Kickstart parameters are mapped to uppercase bash variables prepended with CONF_
# so for example, "domain=example.com" as a kickstart parameter would be "CONF_DOMAIN=example.com" for the script.

# PARAMETER DESCRIPTIONS

# install_components / CONF_INSTALL_COMPONENTS
#   Comma-separated selections from the following:
#     broker - installs the broker webapp and tools
#     named - installs a BIND DNS server
#     activemq - installs the messaging bus
#     datastore - installs the MongoDB datastore
#     node - installs node functionality
#   Default: all.
#   Only the specified components are installed and configured.
#   E.g. install_components=broker,datastore only installs the broker and DB,
#   and assumes you have use other hosts for messaging and DNS.

# repos_base / CONF_REPOS_BASE
#   Default: https://mirror.openshift.com/pub/origin-server/nightly/enterprise/<latest>
#   The base URL for the OpenShift repositories used in the post-install.

# domain / CONF_DOMAIN
#   Default: example.com
#   The network domain under which apps and hosts will be placed.

# broker_hostname / CONF_BROKER_HOSTNAME
# node_hostname / CONF_NODE_HOSTNAME
# named_hostname / CONF_NAMED_HOSTNAME
# activemq_hostname / CONF_ACTIVEMQ_HOSTNAME
# datastore_hostname / CONF_DATASTORE_HOSTNAME
#   Default: the root plus the domain, e.g. broker.example.com - except named=ns1.example.com
#   These supply the FQDN of the hosts containing these components. Used for configuring the
#   host's name at install, and also for configuring the broker application to reach the
#   services needed.
#
#   IMPORTANT NOTE: if installing a nameserver, the kickstart will create DNS entries for
#   the hostnames of the other components being installed as well. If not, it is assumed that
#   you have done so when configuring your nameserver.
#

# named_ip_addr / CONF_NAMED_IP_ADDR
#   Default: current IP if installing named, otherwise broker_ip_addr
#   This is used by every host to configure its primary nameserver.

# broker_ip_addr / CONF_BROKER_IP_ADDR
#   Default: the current IP (at install)
#   This is used for the node to record its broker.
#   Also is the default for the nameserver IP if none is given.

# node_ip_addr / CONF_NODE_IP_ADDR
#   Default: the current IP (at install)
#   This is used for the node to give a public IP, if different from the one on its NIC.
#   You aren't likely to need to specify this.

# IMPORTANT NOTES
#
# You will almost certainly want to change the root password or authorized keys (or both) that are
# specified in the script so that you can access the system after installation.
#
# In order for the %post section to succeed, it must have a way of installing from RHEL 6.
# The post section cannot access the method that was used in the base install.
# So, you must modify this script, either to subscribe to RHEL during the base install,
# or to ensure that the configure_rhel_repo function below subscribes to RHEL
# or configures RHEL yum repos.
#
# The JBoss cartridges similarly require packages from the JBoss entitlements, so you must subscribe
# to the corresponding channels during the base install or modify the
# configure_jbossews_subscription or configure_jbosseap_subscription functions to do so.
#
# If you install a broker, the rhc client is installed as well, for convenient local testing.
# Also, a test user "demo" with password "changeme" is created.
#
# If you want to use the broker from a client outside the installation, then of course that client
# must be using a DNS server that knows about (or is) the DNS server for the installation.
# Otherwise you will have DNS failures when creating the app and be unable to reach it in a browser.
