Introducing smide

Aim of smide:

• e-bike sharing

• Fully managed e-bikes without permanent stations

• Offers an easy way of bridging the “last mile” gap in public transportation

=> Explore alternative solutions for mobility

Speedboat – boon and bane

What is a speedboat for

• Leads out of the business potential of an idea or concept

• Doesn’t matter, if the speedboat turns into a submarine and never reaches

the surface

• Doing all this things, without disturbing the core business

..to be

or

not to be….

Speedboat – boon and bane

Implementation

• Building a minimum viable product (MVP)

• Cost sensitive

• No constraints, no guidelines ... just functionality … only speed matters …

• Security??? WTH is security ...

Results in an operations nightmare

• The MVP isn’t conform to any existing guidelines, standard operation platforms…

• Doesn’t fit to any strategy

• Can’t be or shouldn’t be run in the standard Mobiliar data center

Mobiliar operation:

• Runs the containers

Business

development:

• Project owner

• Defines requirements

• Handles the partners

• Financial responsibility

External

development:

• Implements the requirements

..and now, to come to the point…

Docker

• Contractors create Docker images which can be easily shipped to the Mobiliar

• An dedicated Docker registry helps separate the containers from the internal and the external companies

• The helping hand of Kubernetes deploys any necessary certificates, configurations and the deployment files

• NFS is used to persist data from the containers.

• Backup and restore are provided by Mobiliar internal tools

Challenges

• We have decided not to use the Mobiliar CI / CD chain (Teamcity, AMW) in the public access cluster at the moment

A separate solution is a huge amount of work

• The customer ships images directly, instead of code. Configuration is delivered separately

Manual deployment

• Communication between business development, external partners and Mobiliar operations

Find a channel and use it!

• One speedboat is working and the next is coming => Multi tenant?

Security handled by Kubernetes with certificates

Network separation could work by using Calico instead of Flannel (or Canal)

But Docker?

… under the hood

Operations

• Die Mobiliar is using Kubernetes heavily for the whole agile build/deploy chain

• Separate Kubernetes cluster for

Development

Preproduction

Production

• Need of a Kubernetes Test Lab cluster, testing new versions (Kubernetes, Docker, Etcd, Flannel, etc.)

• Extra Kubernetes public cluster (speedboats) for

Preproduction

Production

Operations - Monitoring

• With Prometheus and Grafana you can have an optimal Kubernetes single cluster monitoring system.

28.10.2016Build a speedboat harbor using Docker 18

Operations - Logging

• Logfiles can be analyzed using Splunk which is implemented in the Mobiliar. Labels can be helpful!

The external partners are using the Kubernetes way of obtaining them.
