Provide Spark with cross-account access
Provide Spark with cross-account access

In case you need to provide Spark with resources from a different AWS account, I found that quite tricky to figure out. Let’s assume you have two AWS accounts: the alpha account where you run Python with IAM role alpha-role and access to the Spark cluster; and the beta account where you have the S3 bucket you want to get access to. You could give S3 read access to the alpha-role, but it is more persistent and easier to manage by creating an access-role in the beta account that can be assumed by the alpha-role.

Upload Gitlab CI artifacts to S3

With GitLab CI it is incredibly easy to build a Hugo website (like mine); you can even host it there. But in my case I use AWS S3 and Cloudfront because it is cheap and easy to setup. The CI pipeline to build and upload the static website is also straightforward with the following .gitlab-ci.yml: variables: GIT_SUBMODULE_STRATEGY: recursive stages: - build - upload build: stage: build image: monachus/hugo script: - hugo version - hugo only: - master artifacts: paths: - .

Kubernetes for the hobbyist with Kops

Earlier I posted about my hobby cluster on GKE which I want to keep under an affordable budget. Unfortunately Google Cloud will start charging a management fee from june 2k20 of 10$ct per hour (=$73/mnth) just like AWS. If they unilaterally change the rules, let’s get out of here! I’m thinking of moving to a self-managed Kubernetes cluster on AWS with spot instances: 1 x 1GiB master-node (t2.micro spot instance, $2.

Deploy to ECS Fargate with Jenkins
Deploy to ECS Fargate with Jenkins

In this post I demonstrate a simple container deployment setup; a Jenkins pipeline to Elastic Container Registry (ECR) and Fargate on Elastic Container Service (ECS). I assume you have Jenkins running, with a pipeline and Git repo webhook tied to it. Besides the default Jenkins plugins, you’ll need the Pipeline Utiliy Steps. Also I assume you already have a ECR repository, a ECS Fargate cluster and an AWS service account with credentials.
