What is it like to interview at Docker, Inc?
Several different talks (4) some are technical some others are not. For a SWE classic technical interviews data structures corner casesplexity both in time analysis technical questions about the field you want to work in. Everyone is very kind willing to know about you in depth and about your desire to on this project. They take a lot of time to answer any question you might have and seem much more passionate to be honest than all the otherpanies Ive applied to until now. If you are interested in the project definitely go for an application the interview process is very coolpared to most.
Why is Docker Inc. in bankruptcy when it is widely used?
It is not in bankruptcy they are looking for funding before that happens. Because docker (application) is open source it is available to use free of charge (themunity edition - CE). CE is very widely used which does not earn Docker pany) any money. Docker makes money from providing support consulting and the Enterprise Edition (EE) which does cost money. These 3 things are not providing the ie that Docker had hoped thus the memo that was released (leaked?) making it look worse than it probably is.
What type of coding questions are asked in the interviews for Docker, Inc.?
Im glad I can help this Question thread. Since I have worked on Docker and I know a lot of other Docker practitioners I can feel this answer would be of help. Docker Interview Questions italic What are the differences between Docker and Hypervisors? Can High Availability be achieved with Docker? If so how? How have you used Docker in the past? Will you loose data when the Docker container exits? ordered-list Im sure you want to also see the answers for these questions. If so go to the below s.

Startup Business Models: Will Docker, Inc. become profitable in the next years?
Containers represents a fundamental shift in cloudputing landscape and Docker as apany will unlock immense value being a leader in this change. I believe the majority of revenue wille from upgrading enterprise customers to the microservice architecture and there will be lot of gaps to to be plugged in the area of networking storage and orchestration with the new approach. Docker would need to focus itself as a servicepany at some point of time (or perhaps engage with some strong partners) to help enterprises in this transition.
Which should I choose, Chef, Puppet, Ansible, SaltStack, Docker, or something else if I’m looking to lead an effort to improve automation in the infrastructure of a global agency with dozens of simultaneous client-specific projects?
I've used Puppet Chef and SaltStack. A few years ago I investigated Ansible and for multiple reasons (one of them in particular the emphasis on creating a dependency graph of states) chose SaltStack. I really enjoy SaltStack. It's a nice paradigm and aplete solution. Granted I'm most experienced with SaltStack so the depth of my understanding of what other tools have to offer is skewed towards SaltStack. With SaltStack I can do this With a singlemand bring up a new Amazon instance. Have the salt master (a server responsible for managing the state of your cluster) react to the new instance being up pull the ssh host key sign it and distribute the cert. Once the instance has finished deploying the application I can register with the load balancer and then I can register a service with the salt master with specific details like the new instances private-ip. After the service is registered AND ONLY AFTER IT IS DONE DEPLOYING I can regenerate my monitoring configuration to include the new instance with the rules. Also if my service needs to know it's peers I can also automatically update my peers configuration in response to a new service registration. I can do this in rolling fashion (with the orchestrator) or all at once. SaltStack is aplete solution and does more than just configure a server. How you perform these s of tasks with other tools is something to keep in mind. The salt reactor orchestrator cloud-driver and salt-mine work together to elegantly solve the problem of managing and orchestrating cluster state. Plus it's an open source project with a very weingmunity. Worth of note SaltStack is also incredibly simple to install! The master doesn't have any special dependencies on a message queue or a special database in order to do it's job. Installing a minion on a myriad of Linux distros is quite easy also using the bootstrap script provided by saltstack. SaltStack is ubiquitous. It runs everywhere even servers that don't have SSH installed. SaltStack has a decent security model. Each minion gets a specific cert pair which allows them to connect as a certain ID. This ID can be used to limit the amount of cluster secrets they can access. A few years ago when I left Puppet and Chef orchestration meant pulling and applying state in cron-fashion periodically. I feel this is one of the worst ideas ever toe to ops tools and it made their application deployment story aplete joke. While the orchestration story in both of those tools has since improved it's been nice that orchestration has been a focus of SaltStack from day one. So to summarize SaltStack is aplete solution SaltStack runs everywhere SaltStack encourages a more declarative approach to configuration SaltStack has had a focus on orchestration since day one SaltStack is simple to learn SaltStack is fast SaltStack is extremely likely to be able to meet your needs (LinkedIn uses SaltStack... so if you're smaller than LinkedIn... you're in luck!)
Is it true that open source companies will never be major corporations?
These things are hard to predict but there are some active growingpanies built around open source projects so it certainly possible. I can think of a few examples off the top of my head Docker inc built around the Docker container system recently raised ~$1M and has definitely been making waves in the Silicon Valley tech scene. MongoDB inc (formerly 1gen) is based around the open source NoSQL database Mongo DB GitLab is an up-anding GitHubpetitor with their core software entirely open source RethinkDB is another databasepany like Mongo but smaller (I believe) and with a much better technical reputation Cloudera provides an Apache Hadoop distribution with enterprise support and additional tooling Some of thesepanies might be better-described as open core rather than open source because they sell some italic proprietary tools to their core projects. But theyre all squarely centered around open source development and spend a lot of engineering effort on the underlying open source project. None of them are as big as the Googles and Amazons of the world but mostpanies aren. They are italic seriouspaniesCloudera for example has 1 employees and a private valuation in the billions. Will any of them succeed? Who knows. They might they might not. Perhaps some other open sourcepany will make it big instead. But I don see anything that preventing apany centered squarely on open source technology making it big one day.
