Ansible Playbook to install a complete Apache Mesos stack

Donate Support Chat

This playbook deploys a full Apache Mesos stack. The access to mesos (agent and master) need credentials. The default one is "marathon:marathon".

Requirements

  • CentOS 7 (deprecated) or Debian/Ubuntu:[focal|jammy]
  • Ansible Galaxy collection: community.general
  • Ansible version:
$ ansible --version

ansible [core 2.14.2]
  python version = 3.10.9 (main, Dec  6 2022, 18:44:57)
  jinja version = 3.1.2
  libyaml = True

Informations

  • These playbook will install cronjobs to cleanup unused docker images, containers and local volumes. To besure that local volumes will not be deleted, add a tag called "mesos" as label. As example:
docker volume create --label tag=mesos volumename
  • These playbook will not restart services. If you apply new configuration and want to restart the service, use the tag "restart"

How to use

Install the whole stack

ansible-playbook -i ../inventory/inventory/mesos plays/server-config.yaml

ansible-playbook -i ../inventory/inventory/mesos plays/server-config.yaml --tags update

Restart all daemons

ansible-playbook -i ../inventory/inventory/mesos plays/server-config.yaml --tags restart

Reconfigure DNS

Persistent Storage

For persistent container storage, we recomend to use our ansible-docker-volume playbook to deploy S3 docker-plugins as systemd service.

Troubleshooting

Missing ping between containers

If weave cannot ping between containers at different hosts, you have to change the following configuration:

sysctl net.bridge.bridge-nf-call-iptables=0

Do not forget to make it persistent.

To many open files

If you get the error message "To many open files" but file-max looks fine, then it could be helpful to resize max user instances:

sysctl fs.inotify.max_user_instances=8192
