Amazon ECR Amazon Elastic Container Service is one of the cheapst ways to store docker images and safer due to the nature of Amazon IAM....

This is a short post on log rotating AWS Elasticsearch indices easily using curator In the past I’ve made a simple docker container with curator and with a simple actions file for managing indices. This worked great on my own installation of Elasticsearch that managed our logs on a small scale. The actions file was: --- actions: 1: action: delete_indices description: >- Rolling indeces accoring to filters options: ignore_empty_list: True #disable_action: True disable_action: False filters: - filtertype: pattern kind: prefix value: filebeat- - filtertype: age source: name direction: older timestring: '%Y....

Using AWS Lambda has become very popular. Most of the time using it is fast and just (but not always). When you start having a lot of lambda functions the complexity of managing them can be hard. When a developer can just edit the code inline, it can become the worse manage service use ever chose. So again, the most important thing to do when you start working with Lambda is to have a proper way to deliver the code from git to aws....

Docker has become the preferable way and the most easy way to run continuous integration, due to its reproducible nature and fast learning curve. There are multiple ways approaching CI processes using docker. Using docker build, which is the easiest way FROM node:12 ARG NODE_ENV=production COPY . /src RUN npm install WORKDIR /src CMD [ "node", "app.js" ] Using docker multi step build, this usually helps making the final image smaller and safer without all the build binaries FROM maven AS Builder COPY ....
