You mentioned something along the line that Dockerfile is self documenting and that you can run the comands in a Virtual Envonment by copy and pasting, is there any tool that can take all the insrtuctions from Docker and just run them on the machine directly so automating the process making the Dockerfile more reusable ? |

how is load balancing handeled? |
| 16:33 |
|
D-Spair |
But we have yet to make the jump to a container orchestration system, mostly due to the lack of large numbers of containers. |
| 16:34 |
|
D-Spair |
jj: There are a number of ways... Some people use ha-proxy, others use external load balancers, and still others use something like Apache ZooKeeper or Consul |

are the resources declared in the job description file (such as cpu = 0.1) blocked exclusively for this pod/container? (independent if the resources are actually used) |
| 16:40 |
|
D-Spair |
Ideally, if you want to load balance across multiple nodes for large scale, you will want to use some sort of API to automatically add instances to the load balancer. |
| 16:40 |
|
|
mccania joined #virtualJUG |
| 16:41 |
|
D-Spair |
mroderus: It's optional... You can "reserve" resources or you can "limit" resources... IF you "reserve", only that container can use those resources. If you "limit", the resources can be shared. |

you can start it with kubectl proxy --www=. |

then it starts on port 8001 |

can my applications themselves make use of the loadbalancer for communicating between them, without the need of a discovery service (i.e zookeeper) ? |
| 16:43 |
|
Rob_Brem |
is it right that the service/load balancer is not aware of the session if there are multiple pods. how do I handle statefull applications, configure my own load balancer to redirect the user to the same pod or doing session replication with something like hazelcast? what would you suggest? |
| 16:44 |

would I define a dedicated load balancer for each of my services (for inter-service communication) or does this only make sense for services that are exposed to the outside world? |
