You can either install docker on your own machine or you install on the SciComp test server farm
On Your Local Computer
It’s recommended (but not required) that you install Docker on your workstation and develop your image on your own machine until it’s ready to be deployed.
On the SciComp Test Environment
You can deploy your own docker machine on the Proxmox virtual test environment in ca 60 sec using the
This environment uses multiple large memory machines (16 cores, 384GB memory each) which are re-purposed previous generation Rhino class machines.
Login to Rhino via ssh and follow these quick steps to run your own docker host. Pick a new host name (in this case we pick
sausage) and make sure it does not already exist, ping should respond “unknown host”
petersen@rhino:~$ ping sausage ping: unknown host sausage
Now bootstrap a new machine
sausage using the “prox new” command with the –docker option and your HutchNet password.
petersen@rhino3:~$ prox new --docker --no-bootstrap sausage Password for 'petersen': installing on node "proxa3" creating host sausage with ID 121 in pool SciComp ...UPID:proxa3:00001F6C:00F2DBDE:57EE629A:vzcreate:121:petersen@FHCRC.ORG: Starting host 121 .. ...UPID:proxa3:00001FB3:00F2E185:57EE62A8:vzstart:121:petersen@FHCRC.ORG: Machine 121 : running, cpu: 0% waiting for machine sausage to come up .. hit ctrl+c to stop ping PING sausage.fhcrc.org (188.8.131.52) 56(84) bytes of data. 64 bytes from sausage.fhcrc.org (184.108.40.206): icmp_seq=1 ttl=63 time=3.17 ms
The prox command checks that the machine is up, now you can login as root with the prox ssh command or by using your Hutch net password.
petersen@rhino:~$ prox ssh root@sausage Welcome to Ubuntu 16.04.1 LTS (GNU/Linux 4.4.19-1-pve x86_64)
Verify that docker works as expected by running the hello world container.

This message shows that your installation appears to be working correctly.
Now let’s assume you would like to install multiple machines to build a small cluster. Each machine requires some ad hoc configuration and we want a little more disk and memory. warning: Each machine requires its own IP address and there are a limited number of IP addresses in the subnet of the development cluster. Try not to deploy not more than 10 machines at a time.

After you are done with your work you can stop and then destroy these machines.
petersen@rhino3:~$ prox stop sausage1 sausage2 sausage3 Password for 'petersen': UPID:proxa2:000060FE:01121EA2:57EEB2A1:vzstop:116:petersen@FHCRC.ORG: UPID:proxa3:00006110:01121EB3:57EEB2A1:vzstop:118:petersen@FHCRC.ORG: UPID:proxa4:00006127:01121EC6:57EEB2A1:vzstop:121:petersen@FHCRC.ORG: petersen@rhino:~$ prox destroy sausage1 sausage2 sausage3 Password for 'petersen': UPID:proxa2:000061C7:01122C18:57EEB2C4:vzdestroy:116:petersen@FHCRC.ORG: UPID:proxa3:000061CB:01122C2A:57EEB2C4:vzdestroy:118:petersen@FHCRC.ORG: UPID:proxa4:000061CF:01122C3B:57EEB2C4:vzdestroy:121:petersen@FHCRC.ORG:
Important: If you stop a machine with the ‘prox stop’ command the host name will not be purged from DHCP/DNS. If you want to re-use that hostname you need to wait for a couple of days. However, if you login to a machine and shut it down with the ‘shutdown -h now’ command the hostname will be released immediately and you
can re-use right away after destroying the machine. This trick does currently only work with the default machine which is based on Ubuntu 16.04. It does not work (as of December 2018) if you use Ubuntu 18.04, such as:
petersen@rhino3:~$ prox new --docker --ubuntu 18.04 --no-bootstrap sausage
Using pre-made Docker images with application stacks
You may not need to create your own Docker image, but that depends on what you want to do. If you are using software that is readily available, there is probably already a Docker image containing that software. Look around on Docker Hub to see if there’s already a Docker image available.
SciComp is also developing Docker images that contain much of the software you are used to finding in
/app on the
rhino machines and
beagle clusters (here’s the R image).
If you’ve found an existing Docker image that meets your needs, you don’t need to read the rest of this section.
Create your own Docker image and put your software inside
You really need a GitHub account to properly build docker containers. Please see our Shiny app example on how to create your own docker image
Deploy your Docker image to production
Your own machine or the SciComp test farm are likely poor choices for running production level applications in containers. For production deployments you will need a GitHub account. (see above)
Using docker hub
Dockerhub is a good choice for fully public open source projects
Push your Dockerfile to a GitHub repository

Using the Fred Hutch Container environment
SciComp supports 3 Rancher environments for hosting docker based web applications:
|SciComp||Internal only SciComp managed applications|
|SciComp-ext||Publicly accessible SciComp managed applications|
|HDC_Local||HDC application environment (currently hosting HICORIQ)|
