DigitalOcean: Private Networking Released

You’ve requested it, and now it’s here! DigitalOcean is happy to announce that all droplets in NYC2 are now equipped with Shared Private Networking, allowing them to communicate with other droplets in that same datacenter. You can enable shared private networking on your Droplet from the Droplet create screen. Traffic sent between Droplets across the private network will not count towards the bandwidth costs and can be used for database replication, file storage, and similar host to host communication. Check out our full length tutorial on how to set-up and use Shared Private Networking. Sign up or login at https://www.digitalocean.com/

Chef – ERROR: EOFError: end of file reached

Recently when using opscode’s chef server and knife I was getting the error message: ERROR: EOFError: end of file reached When trying to execute commands like knife client list I ended up finding out that the problem has to do with how the configuration for chef 11 has changed from chef 10. In your knife.rb file there is a line that gives you the default address / address of your cloud server – you will even see the default if you are running the interactive knife configuration tool (knife configure -i): Please enter the chef server URL: [http://chef.example.com:4000] The big changes for chef 11 are two hard to spot things for the new chef server / knife access url: https://chef.example.com Port 4000 goes away The server now runs on HTTPS / SSL (which implies port 443) Change this to use SSL / HTTPS and your ERROR: EOFError: end of file reached message will go away. I was getting that error when trying to access chef on port 5672 which is the port that RabbitMQ runs on.

ec2 server create syntax (man page)

This is the knife create syntax page. I was trying to launch an instance of Chef with the “knife create” command that chef’s knife provides. The documentation page gives this example for how to launch a web server on Amazon’s EC2 server, but without much explanation of the terms: knife ec2 server create -r “role[webserver]” -I ami-2d4aa444 –flavor m1.small -G www,default -x ubuntu -N server01 After doing some searching I just ended up digging into the code and found this information quite helpful, and so I am sharing it: -f FLAVOR ( or –flavor FLAVOR ) The flavor of server (m1.small, m1.medium, etc) default: m1.small -I IMAGE ( or –image IMAGE ) The AMI for the server -G X,Y,Z ( or –groups X,Y,Z ) The security groups for this server default: “default” -Z ZONE ( or –availability-zone ZONE ) The Availability Zone default: us-east-1b -N NAME ( or –node-name NAME ) The Chef node name for your new node -S KEY ( or –ssh-key KEY ) The AWS SSH key id -x USERNAME ( or –ssh-user USERNAME ) The ssh username default: root -P PASSWORD ( or –ssh-password PASSWORD ) The ssh password -i IDENTITY_FILE ( or –identity-file IDENTITY_FILE ) The SSH identity file used for authentication –prerelease Install the pre-release chef gems –bootstrap-version VERSION The version of Chef to install -d DISTRO ( or –distro DISTRO ) Bootstrap a distro using a template default: ubuntu10.04-gems –template-file TEMPLATE Full path to location of template to use –ebs-size SIZE The size of … Continue reading

10 Amazon EC2 Alternatives

Amazon EC2 Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides resizable compute capacity in the cloud. It is dersigned to make web-scale computing easier for developers. Amazon EC2’s simple web service interface allows you to obtain and configure capacity with minimal friction. It provides you with complete control of your computing resources and lets you run on Amazon’s proven computing environment. Amazon EC2 reduces the time required to obtain and boot new server instances to minutes, allowing you to quickly scale capacity, both up and down, as your computing requirements change. Amazon EC2 changes the economics of computing by allowing you to pay only for capacity that you actually use. Amazon EC2 provides developers the tools to build failure resilient applications and isolate themselves from common failure scenarios. http://aws.amazon.com/ec2/ Digital Ocean Deploy an 512MB RAM and 20GB SSD cloud server in 55 seconds for $5/month. Simple, fast, scalable SSD cloud virtual servers. This competitor was recently featured on Uncrunched and the site boasted, “Digital Ocean v. AWS: 10x Performance For 1/3 Cost”.
