![]() When you're done, click the blue button labeled "Review policy". We're going to immediately fix that in the next step.įor "Resources", we pick "All resources". ![]() It should highlight blue when you've clicked it.įor "Actions", we're going to pick the "All Elastic Container Registry actions" option. Now you'll see this next screen, with a blue button called "Create Policy".Ĭlick "Create Policy" and it will show you a new form with four different sections.įor the "Service" section, we'll search for "elastic container service" and choose it from the search results. You'll know you're on the right page if it looks like this:Ĭlick on "Policies" in the sidebar. ![]() Search for "IAM" and you should see the option for "Manage access to AWS services". You should see a place to search for AWS services. To do that, first go to your AWS web console. In order to use AWS ECR, you'll need to add permissions to your account. Setting up Identity and Access Management (IAM) To get started, we'll need to create an IAM policy, an IAM user, and a container repository. So, we must work with another AWS service, namely the Elastic Container Registry (ECR).įrom here, our cluster will be configured to launch containers on Amazon's services, called Elastic Compute Cloud (EC2) machines. These containers need to be registered with AWS to be used. AWS ECS works by defining appropriate cluster parameters, allowing the service to add or remove machines, based on bandwidth needs or user traffic. Now let's take a look at AWS Elastic Container Service (ECS). □ Without this step, one could easily build and deploy an image that doesn't start up properly, or is not properly connected to the database. Verifying that a container works before deploying will save a developer many headaches.let me tell you. I’m also hoping people with more experience in Ansible and deploying Rails can help me improve it, so that other people who are interested in devops have a reliable (and good) reference.The last blog post showed how to create a Docker image and container locally. I’m hoping this will be useful for people who have considered moving from a PaaS to a IaaS before, but didn’t know where to start. I named the project "Railway"and here's the playbooks it has:ġ - Create a custom AMI with everything a Rails app need Ģ - Create a staging environment with webservers, workers, cache and job redis instances, postgres database and support for up to 9 branches of your app at the same time ģ - Create a production environment with load balanced webservers, workers, cache and job redis instances, postgres database with a read replica ĥ - Deploy to production using rolling restarts Ħ - Update production servers to get the latest security updates ħ - Upgrade production servers to a new AMI with zero downtime Ĩ - Compile ImageMagick and Libvips from source in order to get more up to date versions than what is available in Ubuntu's repositories. So I decided it might be worth to open source the entire thing, if only to save others some of the frustration I felt. Fast forward a few months, and we have an entire repository of playbooks that can, with a single command, do most of the things that Heroku did for us. Main reason was that our clients were on South America, where Heroku does not have a datacenter.Īt the time I did not find a guide on how to do this, so I had to spend an entire week (~40 hours), learning about AWS and Ansible, and feeling like I was continuously banging my head against a wall. At the start of the year I decided it was time to move my company's app from Heroku to AWS.
