pm771, it is, check out http://virtualjug.com/#live |
| 17:15 |
|
D-Spair |
mjremijan: Well, some people do that. The real positive outcome of Docker is that you don't need VMs for application isolation. |
| 17:15 |
|
TaivoKasper |
Docker container is basically a regular linux process, so the performance hit should be close to zero |
| 17:15 |
|
pm771 |
I found it. Thx |
| 17:15 |
|
shelajev |
but that's on linux only |
| 17:15 |
|
shelajev |
so you just get the guest VM out of the box with boot2docker |
| 17:15 |
|
pathfinder |
so I can package a database as part of my application in docker? |
| 17:15 |
|
cesarHGt |
@pathfinder. Yes. |
| 17:16 |

shelajev: Yes, but for production you would probably NOT want to deploy contains to a VM on top of Windows. |

In our environment we have run into issues with the "read-only layers" as it relates to troubleshooting... It's difficult to determine in which layer an error was introduced. |

As such, we are required to run containers which are all built from scratch instead of using existing container layers. |

good point, maybe Arun can say something about debugging the containers? any tips or something |

There are also limitations with how you do networking inside of Docker, but those problems are being addressed by tools like Kubernetes/Weave/etc... |

Guest60826: Every time you run a container is creates a new layer with the changes and thus a new image ID. Those changes are persisted in that new image layer... If you want to persist data OUTSIDE of the container, you use mounted volumes. |

Some more issues we have had running it in production: Running your own internal Docker Hub repository is problematic. Rebuilding containers is time consuming. |

There are nice maven plugins which can build your Java applications into a Docker container for you. |

how can docker and kubernetes be used to have high available solution? |
| 17:38 |
|
D-Spair |
I guess the easiest thing to explain when to use Docker IMHO is that if you are using VMs for application isolation, Docker is a much better solution with lower overhead and is more portable. |
| 17:38 |
|
D-Spair |
Abhijith: Kubernetes can define a minimum number of running instances and if one dies it will automatically provision and launch a new instance. |

Oh, and another thing to keep in mind is the storage system. When you run Docker on ext4/ext3/JFS/XFS/etc.... it uses a virtual filesystem called "AUFS". This filesystem has locking and layering issues which can cause issues. If you use BTRFS or a logical volume as the storage backend for Docker, you will not have those limitations. |
| 17:43 |
|
Guest60826 |
D-Spair : You mean lets if i run a database from mysql image. Where mysql is going to save the files. So that if I run the container again , i should not lost the data |

What happens to the data when the container is killed? Is it also removed? |
| 17:45 |
|
D-Spair |
Guest60826: No... When you run the container Docker creates a NEW container layer which is not named and has a new hash code, so if you try to run the container with the original name, you will NOT get the changes restored. There is an option to tell docker to migrate the name on container shutdown to the updated layer. |
| 17:45 |
|
Guest60826 |
yes , i also have the same question |

Guest60826: aparna: When you stop the container, the runtime image is stored as a new layer with a new hashcode/name... If you start that the original container with the original name, your changes will NOT be present. You could start the image which was created by your original run, but that takes some more work. |
| 17:48 |
|
D-Spair |
The idomatic way to keep persistent data is to use volumes mounted to the container.. |
| 17:51 |
|
Guest60826 |
how to do the volumes |

Guest60826: In the Dockerfile, you define a "VOLUME /mount/path" and when you run the container: docker run -v /external/path:/internal/path container |
| 17:52 |
|
D-Spair |
That will expose the external directory to the container at the mount point specified |
| 17:54 |

Containerception! |

|
Abhijith |
On one hand this setup is brining portability and easy creation of VM (scalability) |
| 18:01 |
|
Abhijith |
aren't we more capable with Puppet, Jenkins, VMWare? |
| 18:01 |
|
Abhijith |
Docker is certainly helpful for development |
| 18:02 |
|
D-Spair |
Abhijith: VMware has a noticeable resource cost. Docker's overhead is SIGNIFICANTLY lower. |
| 18:02 |
|
Abhijith |
I was coming to that D-Spair |
| 18:02 |
|
Abhijith |
Docker is certainly great |
| 18:02 |
|
Timmo |
How does docker/kubernetes handle different architecture ? can we execute containers on ARM processors ? |
| 18:02 |
|
Abhijith |
but kubernetes impressive but I do not see adaptation soon |
| 18:02 |
|
D-Spair |
Timmo: I have run Docker containers on ARM7HF, but you have to ensure that you use packages which are architecture appropriate |
| 18:03 |
|

Arun may be able to answer the architecture question better |

|
D-Spair |
usfch: There's no lower or upper limit... |
| 18:08 |

D-Spair |
usfch: By default, whatever resources your host system has can be used by the containers and there is almost no additional overhead created by Docker. |
| 18:09 |
|
D-Spair |
usfch: So, in a sense, it no different than running the application without the container. |
