Can somebody please help me? I configure three masters following the guide of digital ocean and I'm trying to access the Mesos and Marathon interface using my host only adapter address, but it just says the site cant be reached and refused to connect
Thanks for asking your question. First of all, the document you are referencing from Digital Ocean is from 2014 and while DC/OS can run on Ubuntu it is not a supported operating system for this product. There are also concerning suggestions in this article that I would avoid (such as only have a 2 Mesos Master quorum which it looks like you already noticed). Lastly, the company itself is called Mesosphere and the product is called DC/OS :)
With all that out of the way, since 2014 much has changed in DC/OS and the Digital Ocean document is obsolete. You no longer have to manually configure Zookeeper, cluster quorum size, Marathon, Mesos, edit host files on agents, or any of the other items this document references for a production cluster. All of that is taken care of in a YAML configuration file called config.yaml if you attempt an "advanced" install.
You should have more success with connecting to the UIs (DC/OS, Marathon, and Mesos) by attempting an installation method that is up-to-date, on a tested and supported OS, and using the latest versions of DC/OS provided by Mesosphere. This will remove the difficulties you are seeing from the obsolete documentation.

Hope this helps and you see success with DC/OS!
***Edit, if you want to avoid DC/OS, use the Mesos advanced course https://open.mesosphere.com/advanced-course/

I've been trying to Run cartography on my EC2 account for the last 2 days. I have no previous knowledge of Neo4j, But following their installation process doesn't work.
First I've tried to install Neo4j using rpm instructions for Neo4J website, no success acessing Neo4j on port 7474. Error: Connection refused.
Then I gave up trying to make Neo4J work on an EC2 installation, and used their MarketPlace AMi- Works Like a charm but I don't know what is being installed on that AMI. So I decided to install and run cartography on this instance.
My first problem was installing python, pip and java correctly. After everything working, I've discovered neo4j bolt port used my public IP, not my localhost. After thatI was able to finally execute Cartography, but Not it's giving me the following error:
neobolt.exceptions.ClientError: Supplied bookmark [FB:kcwQ40omSYgvSzKPpCQTXDOcCBSQ] does not conform to pattern neo4j:bookmark:v1:tx
Have Anyone really was able to use this?, every step along the way requires some specific libraries.
Thanks !
I maintain cartography and hope I can help (wish I saw this earlier though haha)
Few things to check:
Are you using Neo4j 4.x? cartography currently only supports 3.5.x.
To run for one AWS account,
AWS_PROFILE=profilename cartography --neo4j-uri <uri for your neo4j instance; usually bolt://localhost:7687>`
To run multiple accounts, set up an AWS config file and run
AWS_CONFIG_FILE=/path/to/your/aws/config cartography --neo4j-uri <uri for your neo4j instance; usually bolt://localhost:7687> --aws-sync-all-profiles
(see https://github.com/lyft/cartography/blob/master/docs/setup/install.md#cartography-installation)
If you have more questions feel free to open a GitHub issue or start a thread on our Slack (can talk about more specialized setups like if you're using containers or anything like that too)
I want to fake an enterprise environment with OpenShift Origin V3 to test some stuff.
I'm going to try the advanced installation with multiple masters, etcds and multiple nodes.
https://docs.openshift.org/latest/install_config/install/advanced_install.html
I already did the quick installation once (running OpenShift in a container) and I did the advanced installation a few times (one host which contains a master + a node, and some nodes).
First of all, I'm installing the whole environment on AWS EC2 instances with CentOS7 as OS. I have 2 masters (master1.example.com and master2.example.com) and 3 nodes (node1.example.com, node2.example.com, ...)
I want to seperate my masters and nodes. So containers and images will only be on the nodes. (So no host which contains a master and a node).
My masters needs to be HA. So they will use a virtual IP and pacemaker. But how do I have to configure this? There are some tutorials to use pacemaker with apache. But there is nothing that describes the configuration of pacemaker and vip for using it in OpenShif.
great news, I had to deal with pacemaker as well but now Pacemaker is not the native HA method for Openshift anymore(from v3.1). So we can get rid of the tedious pcs configuration and fencing tunning.
Now ansible installation playbook's take care of multiple masters installation, with what they called Openshift HA native method. No additional setup is required for a standard configuration.
Openshift HA method takes advantage of etcd to select the active leader every 30s(by default)
There is a method to migrate from Pacemaker to native HA

I installed Cloudfoundry (approximately version v220) on OpenStack and I want to work with private Docker images on Cloudfoundry.
I would like to run docker registry/repository (Doc|Github) server on Cloudfoundry.
I found tutorials on how to install it directly on a machine/VM (1|2|3).
Is there something to be said against running it on Cloudfoundry?
How do I install it?
Is Diego or something like that already providing the registry/repository service?
I thought Diego was part of Cloudfoundry but reading the CF release notes it looks like I have to install Diego separately is that correct (see "Recommended Diego Version")?
It is possible to run private Docker images on Cloudfoundry and there is a CF-specific registry you can use. In order to do that, there are a number of extra steps that you will need to undertake.
To answer your last question first, we must tease apart what exactly is meant by "Diego is a part of Cloud Foundry". Cloud Foundry is deployed using BOSH, which among other things has a concept of a release. A release is in essence a versioned collection of source code, configuration, dependencies, etc. that your system needs to run. I would recommend reading the BOSH docs to gain more of an understanding as to exactly what BOSH is.
Historically, Cloud Foundry has been made up of a single BOSH release, cf-release, but that is no longer the case. Diego itself is deployed as a separate release, diego-release, and that is what is being referred to in the cf-release release notes. To ensure compatibility, each release of cf-release publishes which release of diego-release is being run alongside.
Diego does support an internal docker registry that can run private docker images, but in order to do so, you must deploy another BOSH release and configure it correctly. That bosh release is the diego-docker-cache-release, the README should hopefully help in getting you started. This cf-dev post by the current Diego PM might also be helpful in setting it up. If you run into any problems or issues, I would recommend posting to the cf-dev mailing lists as the CF community and developers maintain a closer watch on that communication channel.
For some time I am managing EC2 (Windows Boxes), RDS and S3 on AWS.
I do know manual steps that must be made in order to set up lets say a normal box (DB, Storage and Server. I heard about Vagrand, but everywhere I looked it mainly talks about Linux boxes on AWS.
My main question is: Is Vagrand a tool that will save me time for deyploment (windows), or should I not use it at all (in Windows scenario).
Vagrant plays nicely with AWS (via vagrant-aws plugin).
Vagrant seems to play nicely with Windows as well since version 1.6 and the introduction of WinRM support (ssh alternative for Windows).
However AWS plugin doesn't support WinRM communicator yet. So you'll need to pre-bake your Windows AMIs with SSH service pre installed, if you want vagrant to provision it.
Update (29/03/2016): Thanks to Rafael Goodman for pointing to vagrant-aws-winrm plugin as a possible workaround.
I'm currently working with a team in my University to put together a new webapp. Nothing too fancy, just run of the mill MySQL + Django. We are also hoping to use Git for source control. We were wondering what hosting options were available to us. We're all very competent with Unix, so a ssh connection would be preferable. We also looked into the Amazon Cloud, but are not sure if that's right for us. What does Stackoverflow suggest for a provider to host both a Git repo for us and our webapp. The simpler, the better. It should also run a Linux environment.
I have had great success using the Rackspace Cloud servers. You get root SSH into the server, so you can set up your Git repo and your web app there. They have a lot of options for which flavor of Linux you want to use as well.
I'm doing Django/Postgres on an Ubuntu server and haven't had any problems at all. As a bonus, it includes very easy web and API integration with their CDN if you're interested in that.
I looked into a variety of cloud providers and RS had the best options for me, although CDN integration was a big deal for my site so that factor weighed heavier than it might for you.
I use the cheapo 256MB RAM/10GB HD install and pay around ~$12/month after bandwidth costs are figured into it.
Here's the pricing: http://www.rackspace.com/cloud/cloud_hosting_products/servers/pricing/
Why not AWS? It has a free tier that is able to run basic Django apps well. You can run it using a Django AMI directly or a service like BitNami Cloud Hosting (Disclaimer: I am a BitNami developer, I am actually in charge of many of the Python-based stacks). Both options allow you to run a micro instance of an Amazon Machine for free (680Mb Ram, 10Gb disk).
On BitNami Cloud Hosting, we recently added support for Python and Django (Python 2.6.5 and Django 1.3) and we already included Git. When you select to create a new server you will have access to all those components on top of Ubuntu 10.04.
Also if you are interested in using Redmine (as dgel suggests) you can select to install it when you create your server in the same machine. Since it is an university project, you may also want to consider hosting the Git part on github.com for free.
I would highly recommend sourcerepo.com for git and redmine hosting. $6.95 per month for unlimited projects including redmine instances with git hooks. You don't need to worry about setting up or maintaining the git repos or redmine instances yourself.
Then for your project's public hosting you can't beat linode.com for $19.95 per month.
