Ansible Playbook to install a complete Apache Mesos stack

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

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
