Mesos on coreOS
30 likes•9,637 views
Mesos on CoreOS provides a summary of deploying applications on a CoreOS cluster managed by Mesos and Marathon. It discusses using Docker for application containers, CoreOS for the operating system, Mesos for resource management and scheduling, and Marathon for orchestrating containers. The presentation demonstrates deploying a sample web application across three servers on the CoreOS cluster, registering the containers with Consul for service discovery, and updating configurations automatically using ConfD.

- 6. 1. Get latest source 2. Install dependencies 3. Restart
- 7. 1. Get latest source 2. Install dependencies 3. Restart
- 8. Failed to install dependencies!! Why??? conflicting library version ruby version is too old gcc version is too old 8080 port already in use unknown error…
- 9. Googling!!
- 10. successfully deploy!! but, migration to another server or scale out?
- 12. 2. DOCKER new container technology
- 13. Docker is an open platform for building, shipping and running distributed applications.

- 24. CoreOS is designed to give you compute capacity that is dynamically scaled and managed
- 25. A Minimal Operating System Painless Updating Docker Containers Clustered By Default
- 26. A highly-available key value store /services/web/web_1 172.17.8.101:49155 valuekey directory
- 30. Require install agent (*not ansible) Too many feature
- 31. Fleet is enough?
- 32. Fleet Distribute systemd = low-level Difficult cluster resource management (No check CPU/Memory/Storage) Lack of health check option Lack of rolling restarts strategy Lack of GUI tool
- 33. 4. Mesos A distributed systems kernel
- 34. Program against your datacenter like it’s a single pool of resources
- 36. Mesos began as a research project in the UC Berkeley RAD Lab Twitter, Facebook, Apple, Airbnb, Netflix, eBay, … using mesos efficient resource isolation and sharing across distributed applications supports a high availability mode (with Marathon) support docker (from 0.20.0) UI available Job Scheduler (with Chronos) support Hadoop, Kafka, Spark
- 37. mesos (with marathon) fleet configuration JSON low-level shell command cluster resource management yes no health check http with many option process check rolling restart strategy yes no GUI yes no
