036 Getting started fast with Docker, with Mark Drew

By Michaela Light Leave a Comment

Mark Drew talks about “Getting started fast with Docker” in this episode of ColdFusion Alive podcast with host Michaela Light. In this presentation, Mark Drew will go through the fundamentals of the Query Language, structure, use cases and how we can get started with GraphQL endpoints.

In a world where APIs and REST are the way that we can communicate with services, it can become an arduous task to get to the information you need.

For example, if you look at a single tweet, obtained from Twitter's API, you will so a stack of information that you don't need! If only there was a way to query this data to get just what you need.

Enter Facebook's GraphQL language. A language specification that solves the same problem that SQL did for Relational Databases.

And to continue learning how to make your ColdFusion apps more modern and alive, I encourage you to download our free ColdFusion Alive Best Practices Checklist.

Because… perhaps you are responsible for a mission-critical or revenue-generating CF application that you don’t trust 100%, where implementing new features is a painful ad-hoc process with slow turnaround even for simple requests.

What if you have no contingency plan for a sudden developer departure or a server outage? Perhaps every time a new freelancer works on your site, something breaks. Or your application availability, security, and reliability are poor.

And if you are depending on ColdFusion for your job, then you can’t afford to let your CF development methods die on the vine.

You’re making a high-stakes bet that everything is going to be OK using the same old app creation ways in that one language — forever.

All it would take is for your fellow CF developer to quit or for your CIO to decide to leave the (falsely) perceived sinking ship of CFML and you could lose everything—your project, your hard-won CF skills, and possibly even your job.

Luckily, there are a number of simple, logical steps you can take now to protect yourself from these obvious risks.

Interview transcript

Michael:          Welcome back to the show. I am here with Mark Drew otherwise known as the amazing C.F.O. from London.

Mark:               There's only one of us in London.

Michael:          There’s only one, others 00:12 [crosstalk]

Mark:               There’s hundreds of them.

Michael:          Yes and he's the director of web development at C.M.D. which is a web development shop, I believe in the U.K.

Mark:               In sunny Greenwich.

Michael:          In Greenwich yes, he got Greenwich Mean Time exactly down. And he's also the co-host of a new podcast called ‘Local Host’. So, check that out too. I’ll put the link in the show notes to that.

So today, we're looking at how C.F.S. can get started fast with Docker and we're going to look at what a Dock container is and why everyone listening should care about that. The challenges they overcome, Docker versus Vagrant even controversially our traditional I.S.P. is going to go away if Docker gets his way.

And how they compare the virtual machines, how you can get started with a Docker engine. What the heck is Docker compose? And using Docker to make your sites even more reliable. Docker cloud and how you can get started with Docker.

So, welcome Mark.

Mark:               Well, thank you Michel for having me on board. This is very exciting all across the internets.
