A very simple script to create local mesos/marathon cluster for debugging purposes
This python script can be used to deploy a local zookeeper/mesos/marathon cluster in an isolated container for debugging purposes. It's developed using only the core python libraries, so you can use it without any hassle.
- docker & docker-compose
- python 2.6+ (no extra packages needed)
Just specify the configuration file to use:
./marathon-dcluster path/to/config.file
The configuraiton file is a simple key = value configuration file that specifies which versions to use, how many instances to launch, which ports to expose and how much resources to allocate.
The minimum required parameters are:
# Which docker image versions to use
mesos = 1.4.0-rc2
marathon = v1.4.7
zookeeper = 3.4The following arguments are frequently used:
--rm: Remove the cluster and remove work directory--reset: Reset the cluster state by wiping the/varcontents in the work directory
You can also override each parameter described below. For example:
--mesos_master_port 8080
The full set of available configuration parameters follows, along with their default values:
### Mesos-specific ###
# The mesos version
mesos = None
# The mesos docker image to use
mesos_image = mesosphere/mesos
# How many slaves and masters to start
mesos_masters = 1
mesos_slaves = 1
# Expose mesos 5050 port on the localhost network under the
# specified port. If more than one nodes are started, each
# consecutive node gets the next port allocated.
#
# For example, for `mesos_masters=3` and `mesos_master_port=5050`
# the ports allocated will be `5050`, `5051` and `5052` for each
# individual master.
mesos_master_port = None
mesos_slave_port = None
# You can also override the auto-detected resources and specify
# a custom values for each one.
mesos_resources_cpus = None
mesos_resources_gpus = None
mesos_resources_mem = None
mesos_resources_disk = None
### Marathon-specific ###
# The marathon version
marathon = None
# The marathon docker image to use
marathon_image = mesosphere/marathon
# Additional marathon command-line arguments to pass
marathon_args = None
# Enable JVM debug on marathon and expose the debugger port
# on the localhost, under the specified port
marathon_debug = None
# Expose marathon 8080 port on the localhost network under
# the specified port. If more than one node is started, the same
# rules as for `mesos_master_port` apply.
marathon_port = None
# How many marathon nodes to start
marathon_nodes = 1
### Zookeeper-specific ###
# The marathon version to use
zookeeper = 3.4
# The zookeeper docker image to use
zookeeper_image = zookeeper
# How many zookeeper nodes to start
zookeeper_nodes = 1
# Expose zookeeper 2181 port on the localhost network udner
# the specified port. If more than one node is started, the same
# rules as for `mesos_master_port` apply.
zookeeper_port = None
