Ask HN: Do you use Vagrant or Docker for active development?

50 点作者 nepger21将近 10 年前

I think I understand the use case of Docker for deployment, but does Docker hold its sway at the moment for active development. Data persistence support is not out-of-the-box. Vagrant with its own isolated and shared volume support seems like something that would be very good in active development of software artifacts. What is the view of the HN mass, and what would you recommend?Apart from these two, are there any others that looks promising?

On a Mac or Windows machine you're using Docker with Vagrant via Boot2Docker anyway.A lot of people us both <a href="http://docs.vagrantup.com/v2/provisioning/docker.html" rel="nofollow">http://docs.vagrantup.com/v2/provisioning/docker.html</a>That's actually the only thing that got me to hold off on Docker the last 2 times I've evaluated it. I was able to get everything running for a 1 monolith + 7 microservice system that I work with but the local developer workflow felt very clunky even with Fig. That was 6 months ago and it's my understanding there have been a lot of improvements.That project was for a Ruby team and there are so many Ruby based tools that make the local development workflow a smooth operation that shoehorning Docker in locally would have been a step back, so we held off on it.It's an area that I think will see major improvement though. Heroku's even gotten in on it.<a href="https://devcenter.heroku.com/articles/introduction-local-development-with-docker" rel="nofollow">https://devcenter.heroku.com/articles/introduction-local-dev...</a>Which is really impressive to me. If anybody in the space can polish out the user experience, it's Heroku.

I recently switched to using both, docker running in a Vagrant VM. I've had several frustrating issues with boot2docker on OSX, it's generally just been less stable for me than Vagrant.In terms of using docker, IMO it's the best development experience I've come across once you get everything set up. It can be confusing to get your workflow set up at first, and it seems like everyone does it a little differently, I'm hoping that best practices will standardize a bit as docker continues to mature.I love having every part of an app (app code, split into a few microservices if you wish, postgres, redis, rabbitmq, etc.) completely isolated, and docker-compose is a great system for linking things together. I also currently don't have any puppet/chef/etc code and love not having to maintain that, in my mind a large part of the need for configuration management tools is dealing with the complexity of diffing two arbitrary states of infrastructure, and with the immuatable approach of docker containers all that complexity disappears.

> Data persistence support is not out-of-the-box.This is actually not the case. Although containers do not share any persistent volumes with the host by default, you can use the --volume option[0] to do so.To answer your question, I've used Docker for local development to run MySQL, Postgres, and Redis inside of containers. Using the aforementioned --volume option, you can share the unix socket opened by either of these services from the container to the host. Otherwise, you can use the --port option[1] to share ports between the container and the host.I've had a generally pleasant experience using Docker for this use case and would recommend it. It's nice being able to start using a new service by pulling and running an image. Similarly, it's nice to have the ability to clear the state by removing the container, assuming you choose not to mount volumes between the container and the host.The only frustration I've run into is running out of disk because I have too many images, but it takes a while to get to that point and those can easily be deleted.[0] <a href="https://docs.docker.com/reference/run/#volume-shared-filesystems" rel="nofollow">https://docs.docker.com/reference/run/#volume-shared-filesys...</a> [1] <a href="https://docs.docker.com/reference/run/#expose-incoming-ports" rel="nofollow">https://docs.docker.com/reference/run/#expose-incoming-ports</a>

Use Vagrant for everything even tiny projects go in a Vagrant container (isolation is the primary win with the ability to do a git clone, vagrant up and be away).Don't use any kind of provisioning on vagrant just straight bootstrap.sh as honestly I don't like them.

I don't use Docker, although I don't have a need for it.As a solo coder, I love vagrant - the whole nature that you can use a configuration file with a script or two to build out an entire VM has so many benefits. Less time to build the VM, easily destroy the entire VM, easily rebuild the entire VM, save drive space by destroying the VM when you don't need it, keep the VM configuration in a git repo, distribute the configuration to someone else to use, and the best is having all the steps used to configure the VM are documented in the config file and scripts.

Vagrant with Docker provisioner:<a href="https://github.com/czettnersandor/vagrant-docker-lamp" rel="nofollow">https://github.com/czettnersandor/vagrant-docker-lamp</a>Much faster than the Virtualbox provisioner, so it's not an "or" decision, the two thing works well together :)

Docker is really great for developing things IMO. I use it in a few ways actually. One thing I've found it really useful for is isolating build slaves in Jenkins (using the docker-cloud plugin in Jenkins).I also like to use it to create test deployments for debugging or evaluating things, for example it's a lot easier to run Hadoop in pseudo-distributed mode inside a Docker container with host networking, than it is to fiddle with running it in a VM and either getting NAT or DNS working just right, or installing it locally. With the Docker container, if anything goes awry, it's just so easy to get back to initial state by killing the container and starting again.As for Vagrant, I like it a lot too, but for different reasons. You can define a set of actions that is a lot closer to installing whatever it is you are developing, instead of baking everything together like you do with Docker, which can be desirable. I have used it in the past for creating virtualized cluster environments for integration testing of distributed systems. I think so far I use the VirtualBox provider, but I'm thinking of re-working some of my past uses of it that don't strictly require a VM to use the Docker provider.

I use docker for the development of FEniCS, an open source scientific computing package written mixing python and c++. FEniCS requires a lot of dependencies which can be hard to compile (PETSc alike) or need version hold (Boost alike). Docker helps to hold the environment constant. We currently plan to have build bots based on docker as well to streamline build testing.When I write code inside docker, I always submit to a git repo like Bitbucket. Data persistency is easy. Besides you can always use --volume, which works out of box in Linux.Vagrant requires some basic shared environment, which is not realistic in my case. For example, I use Archlinux myself and am forced to use old Scientific Linux at work, while many other FEniCS developers use Ubuntu, Fedora, or Mac stuff. It is too painful to write and maintain a Vagrant script for all these (different compiler, boost, blas, lapack and some other 10+ numerical specific stuff). I even tried Vagrant+docker. But in the end, with docker maturing, I switched to docker+bash script instead. It is just more convenient and needs less dependency.So I'd endorse a docker only approach if you mostly use Linux and your project has a diverse group of people.

Working in a consulting capacity, mainly doing LAMP development with a small team. We use a standardized Vagrant image (<a href="https://github.com/readysetrocket/vagrant-lamp" rel="nofollow">https://github.com/readysetrocket/vagrant-lamp</a>) which has cut down on a lot of local environment issues for our dev team.Previously all devs had their own environment (some MAMP/WAMP, some homebrew, some remote, etc) which led to onboarding and support issues. Setting up a standardized recommended dev environment has helped with that a lot - both in terms of reducing project onboarding and getting junior developers up and running.Would love a day where we can build projects as Docker containers and hand them off to our clients' IT teams, but that seems to be a way off.SO thread where the authors of Vagrant and Docker weigh in: <a href="http://stackoverflow.com/questions/16647069/should-i-use-vagrant-or-docker-io-for-creating-an-isolated-environment" rel="nofollow">http://stackoverflow.com/questions/16647069/should-i-use-vag...</a>

I use chef and test-kitchen to bootstrap my dev-VM (vagrant is used by test kitchen). So I have written my cookbooks, and depending on the project, I converge (spinning-up) VMs depending only on cookbooks that I need, eg no java will be installed if the project requires node.js only. In addition the main gain with that, is my dev VMs are totally disposable and they own nothing. Everything is being synced into the VM from my host machine, same with data.Lately I am trying to "dockerize" my backends, so in the case my workspace project needs a mongoDB or an other backend from my architecture, I should be pulling those containers up on converging. That will make my life easier when writting cookbooks for the backend dependencies.I believe you can achieve the same using ansible, chef was a personal taste.

Vagrant with ansible to set it up. 1 build vm, 6 'deployed' vm's and 1 'deployer'.Needs a minimum of 42G ram, 150G disk space and fills its logs at 2G/h. Not great when you are running on a 256G SSD.Building takes 2h+ with ~10% random failure rate due to dependency mirrors and timeouts.The python code is deployed as gziped virtualenvs to the hosts. This actually works pretty nicely as it means you cant just import stuff and have to build stuff similar to 12 factor style(We dont use ENV_VARS/stdout logging though).TBH I still dont really see the point of docker, Im sure it will 'just click' at some point but it hasnt happened yet

Why not both? We use vagrant to create our docker environment - a 3 machine CoreOS cluster. This is so we accurately represent our production environment.We then use our production docker image(s) with some more development appropriate configuration options. Vagrant mounts the user's home directory at /Users/<username>/ inside the CoreOS machines. Then we mount the appropriate folder inside the docker container at where the container would normally expect to find the app's code. This way the developers have live updates without having to rebuild the docker image or anything.

I would put it the other way around. Docker+Vagrant is best used for deployment and hopefully it will be stable and battle-tested enough so I can use it in production.I love the fact that once I configured the dev environment on my PC and I hit the road on the next day I can have exactly same environment on my laptop by running single line - "vagrant up". Not to mention that any dev working on the same project saves himself ton of time but not having to configure everything from scratch.I have not taken the leap of faith yet and I am not using the docker in production but hopefully this will happen soon.

How would you provision the Vagrant box? I would think you'd want to avoid having some Dockerfiles for setting up production servers and some completely different provisioner for setting up development in Vagrant.

I've used Vagrant for a few projects over the past few years - mostly small things like hackathons and such. Haven't used it much in the past year or so though.At my last job we used Docker extensively for developing our main software product, based on a Django + PostgreSQL + RabbitMQ + Celery stack. It's definitely a bit tricky to get your head around at first, but after that, it's very nice being able to just type "docker-compose start" and have a working application with consistent configuration ten seconds later.

Vagrant + Ansible for most things. I have used Docker to rebuild some of my environments, and there's a lot of promise, but some hard issues (especially w/r/t more complicated applications with multiple dependencies) that I'm still hoping to make less-hard before switching more to a container-based workflow.One of my main day-to-day Vagrant configs is encapsulated in Drupal VM (<a href="http://www.drupalvm.com/" rel="nofollow">http://www.drupalvm.com/</a>).

I've used vagrant for a big rails 3 app with a lot of dependencies and services, i.e., solr, a redis backed delayed_job queue, etc.- stuff that would have difficult or impossible to manage on a mac.The vm environment was also as close as possible to the production env, with the same os version, etc.It also greatly streamlined onboarding of new devs. The dev environment setup was a couple of hours instead of a day or two.

My team is currently using the gradle cargo plugin (<a href="https://github.com/bmuschko/gradle-cargo-plugin" rel="nofollow">https://github.com/bmuschko/gradle-cargo-plugin</a>) to deploy to our remote docker machines for testing. This is my first time hearing about Vagrant. What are it's advantages for our use case for active development?

The only use case I had for docker so far was to set up a cross compiler toolchain to produce binaries for an armv7 igep board.It was significantly easier to tell my co-workers to install docker and type `make local` for local binaries and `make igep` to produce a igep armv7 binary by running a docker container.

dolel13将近 10 年前

I use docker extensively for both development and production, using it to mirror the production environment as much as possible. Write code on the host, run on the container. It took me sometime to adjust to the concept but once I did, it was pretty cool.

I use Ansible and Vagrant for active development of client projects. It's a great combo because it ensures my local environment matches production as close as possible and as well I can go from nothing to running environment with a vagrant up.

adamjin将近 10 年前

I use vagrant for all my developments, it was easy for me to setup and play around with some new tools, such as saltstack (configuring master and minions) and reused the same bash scripts to setup the dev env.

Yes, Vagrant only (it is awesome), still not sure what docker does. After setting up a Vagrant VM, I run fabric scripts to build the box for its role

Vagrant and puppet. And it's the same puppet we use for production, so we're as close as we can get.

vagrant is okay, but it's kind of a PITA.
