DevOps and Docker Talk: Cloud Native Interviews and Tooling

In this episode I discuss the differences between the dockerfiles commands of ENTRYPOINT and CMD, and how to use them together for automate container startup tasks.

In this episode, I answer a question about how to control admin access to docker and swarm using roll based authentication.

In this episode, I talk with Kubernetes, Docker, and Swarm instructor Jérôme Petazzoni about how to learn and use Kubernetes, and we answer a bunch of YouTube Live questions along the way.

In this episode I'm live from the show floor at DockerCon with Nirmal Mehta and Nils De Moor as we cover the announcments, our favorite sessions, and take your questions on everything from Kubernetes, K3s, Proxy's, Traefik, Docker Enterprise 3.0, Linkerd, storage replication, and more.

In this episode, I have guests Nirmal Mehta, a Chief Technologist at Booz Allen Hamilton, and Michael Irwin, an Application Architect at Virginia Tech University. We talk about running tech meetups, how to be a community leader, the Docker and ARM announcement (the processor in Raspberry Pi), Docker for Node.js, AWS ARM A1 instances, QEMU, Traefik Proxies, Docker Swarm, Network Time (NTP, SNTP), Let's Encrypt, and more.

In this episode, I am joined by Phil Estes of IBM, Scott Coulton of Microsoft, and Sujay Pillai. We're all working in the DevOps space and discuss topics and open source projects weeks before DockerCon. Topics include Kubernetes, CNCF, ContainerD, CNAB, Rootless Docker, Linux security in containers, and more.

In this episode, I chat with Laura Tacho from CloudBees and Marcos Lilljedahl from iúnigo, both Docker Captains and developers. We take questions from the live audience and discuss topics ranging from the difference between Jenkins and Jenkins X, to Facebook's osquery and other new open source, to Docker's upcoming 19.03 release and its new features.

I answer a question about how to build multiple Docker images from a single GitHub repository. I talk about how to change which Dockerfile Docker build will use, and how to control the path (or context) that Docker builds from.

I answer a question about using TLS/SSL certificates in local development with Docker for microservices and then how to use those certs in production Docker. I talk about Let's Encrypt, Traefik, and more.

Docker Captain Michael Irwin and I discuss Java .war files in containers, and how you should break them up. We answer a question on how to design them for easy isolation and replacement.

Docker Captain Michael Irwin and I discuss backups of databases in a container cluster like Docker Swarm.

Docker Captain Michael Irwin and I go over various storage options for persistent volumes in Swarm, and how you need to think about storage for Docker.

In March of 2019 I talked with Michael about the new "docker-app" experimental tool. This clip talks about why it exists, and how to use it. In April 2019 Docker released a beta of 19.03 that includes "docker-app" as a plugin to the standard docker CLI, as "docker app", but most other features of this tool stay the same. We also talk about the standard behind this tool, CNAB.

In this episode, I list the steps to copy or sync files between a docker volume and the host

In this episode I quickly list the steps to setup a Docker Swarm in AWS using docker-machine and shell scripts
