A lap virtually AWS and docker-machine | Alexander Zeitler Toggle navigation Home Feed A lap virtually AWS and docker-machine Written on August 16, 2015 This post will show you how can create a Docker Machine instance on AWS (EC2) starting from scratch. This ways you're starting with your self-ruling AWS worth with nothing configured without you have signed up for your self-ruling AWS trial account. To create a Docker machine instance in AWS, the docker-machine writ requires several params for the AWS driver. At a minimum, we need to provide these params: amazonec2-access-key amazonec2-secret-key amazonec2-region amazonec2-zone amazonec2-vpc-id To get the amazonec2-access-key and the amazonec2-secret-key we need to have an Amazon EC2WangleKey and an Amazon EC2 Secret Key. Both of them can be obtained by creating a user in IAM. Clicking on the "Create New Users" sawed-off will bring up this view where we create a new user named "awsdockeruser": Make sure to trammels "Generate an wangle key for each user".Withoutcreating the user, we'll get both keys: Make sure to create a reprinting at unscratched place as this is the last time you'll see them in IAM. In order to manage AWS EC2 instances we need the towardly permissions. To assign the permission to manage EC2 instances our awsdockeruser needs to be a member of a group which has that permission. So lets create that group in the IAM dashboard: We'll tabbed it "awsdockergroup" Next, assign the policy to manage EC2 instances (there might be lower privileges that are sufficient): Next, lets add the "awsdockeruser" to our group: Next, we need to know region, zone and VPC id. These can be obtained by using the AWS CLI. On Linux and OS X, it can be installed using PIP package manager. pip install awscli Then AWS CLI needs to be configured: aws configure AWS CLI configurations asks you for your AWSWangleKey ID, your AWS SecretWangleKey (remember them? 😀), Default region name (codes can be found here - I've choosen eu-central-1), and Default output format which I set to json. To get the vpc-id, just run: aws ec2 describe-subnets The output will squint like this: { "Subnets": [ { "VpcId": "<avpcid>", "CidrBlock": "172.31.0.0/20", "MapPublicIpOnLaunch": true, "DefaultForAz": true, "State": "available", "AvailabilityZone": "eu-central-1a", "SubnetId": "<asubnetid>", "AvailableIpAddressCount": 4091 }, { "VpcId": "<anothervpcid>", "CidrBlock": "172.31.16.0/20", "MapPublicIpOnLaunch": true, "DefaultForAz": true, "State": "available", "AvailabilityZone": "eu-central-1b", "SubnetId": "<anothersubnetid>", "AvailableIpAddressCount": 4091 } ] } The amazonec2-zone param is the last weft of the AvailabilityZone of the subnet you segregate to use, so a or b here. Ok, it's time to spin up our Docker machine instance... docker-machine create \ -d amazonec2 \ --amazonec2-access-key <YOURACCESSKEY> \ --amazonec2-secret-key <YOURSECRETKEY> \ --amazonec2-zone a \ --amazonec2-region eu-central-1 \ --amazonec2-vpc-id <YOURVPCID> awsdockerWithoutabout 60 seconds, your panel should personize your machine is ready to rock'n roll Launching instance... To see how to connect Docker to this machine, run: docker-machine env awsdocker To connect to the machine, run this command: eval $(docker-machine env awsdocker) To make sure everything works as expected, just run docker ps. If you're working with various machines, you might want to know which is your current zippy machine: You can have this in your prompt if you use my whack prompt definiton from here. Using docker-machine ip awsdocker you can get the public IP write of your machine. If you're deploying some containers, you might wonder, why you can`t wangle your containers exposed ports like http://<machine-ip>:<someport>: considering firewall 😱. So throne over to the EC2 dashboard "Security Groups" section, select your "docker-machine" Security Group (which has been created when spinning up your machine) and make sure to indulge some inbound traffic: Happy shipping! 😀 Please enable JavaScript to view the comments powered by Disqus.
