Infrastructure as a code… I hear about it during at least last 5-7 years. There are a lot of activities in each company (I hope) to introduce configuration management like Ansible, Puppet, Chef, etc to achieve Continuous Integration and Continuous Deployment(Delivery) aka CI/CD. I saw a lot of successful implementations for CI/CD for small and mid-size projects. It’s harder to introduce full automation on big projects but it’s absolutely doable....
Vue.js, global variables and TypeScript
Published at January 15, 2019 · 2 min read
It’s pretty easy to pass some environment variable to Vue.js application using webpack.DefinePlugin. You just need to have something like a sample below in your webpack.config.js: var webpack = require('webpack') module.exports = { // ... plugins: [ // ... new webpack.DefinePlugin({ 'BUILD': JSON.stringify(0.0.1') }) ] } It’s a common way to pass some environment variable into your JavaScript application. Technically, webpack.DefinePlugin injects a global variable into your JavaScript application. You may need it for some feature flags or some global configuration....
Front End Development Is Too Complicated
Published at January 14, 2019 · 2 min read
It becomes more and more complicated. Single Page Applications (SPA) are a great thing. I’m pretty sure that all users like it. I don’t know if many developers like it or not. Personally, I think that its development is too complicated. Maybe it’s not so complicated as I think if you are Front-end Engineer or even full-stack JavaScript Developer. But it becomes extremely hard if you need to integrate your SPA with Python-based API with is working behind Nginx in Docker or Kubernetes....

If you decided to use SVG images as icons in your UI it becomes extremely important to have these images with different colors. E.g. you need resource status icons for ‘available’ and ‘not available’ states. You can use the same SVG for both of these states but fill it with red or green color depending on the state. It’s one of the possible use cases which could be covered by svg-transform-loader library....
Software Development Is Like a Puzzle
Published at January 12, 2019 · 1 min read
Software development often looks like a puzzle assembling. You need to fit a few pieces together to make something working. It’s OK when you need to create something fast. Like a new web site on an existing engine with several new features. There are a lot of libraries, frameworks, engines almost for any case. I’m happy that I still can create something new. Something I can’t google about. Something nobody asked and answered on StackOverflow....

Since I started blogging in English, I think I can translate some useful posts even they were written a few years ago. It’s a translation of the same post in Russian I’m tired to blog the same so I created this blog post to have everything in one place. Set username/email for git: $ git config --global user.email "e0ne@e0ne.info" $ git config --global user.name "e0ne" You can omit to set it global and it will be set only for the current repository....

Five years ago I wrote the post Git: some useful commands (in Russian). Probably, it’s a good idea to translate it into English too but it’s a different story. I used that post as a handbook for some git commands which I had to use really rare. Now I would like to create a similar list for Docker. Some of these commands you can easily find in the manual and help but if you’re such lazy as me, you would like to get such list noted somewhere....
I'm too lazy to not use Bootstrap
Published at January 9, 2019 · 2 min read
I never liked hit with CSS. I hate to deal with HTML make up a lot. I prefer to work with JavaScript and omit styles if possible. Maybe it’s only because I’m not an expert in this area. That’s why I use Bootstrap framework where it’s possible. It allows everybody to create pretty good UI’s for web application with minimal knowledge of styles and CSS. In a real word, I don’t even want to use Bootstrap directly in web applications based on modern libraries and frameworks like React and Vue....
Vue.js + Python API + Docker in Development Environment
Published at January 8, 2019 · 3 min read
NOTE: All things described in this post could be not 100% correct. I just described my development environment for a simple project with JavaScript fronted and Python backend. Everything located in the same repository to make example less complicated but it also could work well for small projects and/or when backend and frontend are implemented by the same team. Any contributions are welcome! Intro It’s a story about how I tried to create a simple development environment for web project with Python-based backend and frontend written on Vue....
Minimal OpenStack Cinder setup
Published at January 7, 2019 · 2 min read
During OpenStack Cinder development you may want to have some minimal working configuration to run the only Cinder on your environment. If you don’t need to test full volume attach flow with Nova, you may need to run only Cinder(cinder-api, cinder-scheduler, and cinder-volume, even cinder-backup is optional), RabbitMQ, and MySQL. Usually, for Cinder development, I don’t need full OpenStack up and running on my virtual machine. I just need to have only Cinder itself and such required things like database and message queue....
