I need to bootstrap 5 etcd containers onto a single node (temporary measure, eventually they’ll have their own nodes). I’m not sure of the best way to go about it, I’ve tried many ways, with no success. The etcd nodes will talk with patroni services on other VMs. Here’s what I’ve tried: I’ve built dockerRead more

Tenho um serviço HTTP que estou a disponibilizar dentro dum docker container. Até agora, para todos os meus serviços HTTP eu criava uma regra de redirecionamento (URL Rewrite) no IIS que permitia que os meus serviços estivessem disponíveis numa porta diferente da porta padrão do HTTP (a porta 80). E também permitia que as minhasRead more

I have a python package that I wrote and I want to use it within multiple docker builds. However, I can’t just install my local package situated outside of Dockerfile folder. And I don’t want to copy the package into multiple projects. So how do I keep my architecture DRY?Read more

Say I have a fairly standard web app, I might have three containers to start: A static frontend (say an nginx server) A backend API server (say node) A database (say a mongo image) The question I have, how should I structure this project? Would I just have a separate git repo for each dockerRead more

When it comes to tests, I can think of two options: Put both test and application in one image. Include only application code in the image. Create a test-specific container that builds after the main image and adds some layers to it (test code, dependencies etc). With the first option, I can test the containerRead more

I am developing my app in a Docker environment to mirror the production environment as closely as possible. Therefore, the build speed is important to have a high iteration speed. The command that takes the longest after making iterative changes (not changing Python dependencies) in my build script is RUN chown -R flask:flaskgroup /home/flask IsRead more

Venho batalhando já a 9 horas para conseguir fazer uma integração continua entre Github > Travis-ci e Docker hub. Até aqui já consegui atingir o seguinte objetivo: aplico um push para o Github, neste momento o Travis-ci “captura o código” e inicia a geração da build, correndo tudo bem faz o deploy no Docker hub…Read more

Preciso de um help, galera. Meu cenário é o seguinte: Tenho o Windows 10 instalado no meu computador. No Windows 10 eu instalei o Virtualbox. No Virtualbox eu criei uma VM e instalei o Debian. Agora, dentro do Debian, eu instalei o Docker. No Virtualbox, eu adicionei o compartilhamento de uma pasta do Windows paraRead more

As an example, Heroku’s “dynos” are virtual machine instances running a variation of Linux. Heroku and most cloud providers can handle dockerized apps. I imagine the security is at the very least monitored on SaaS platforms like Heroku, as opposed to simply running the app on your own – configuring firewalls, managing user privileges, etc.Read more
