DockerCon thoughts..

So I had the great pleasure to attend DockerCon in San Fran this year, and what a DockerCon it was. It seems every year the number of "its my first ever DockerCon" attendees keeps increasing, which is a great sign for the technology's adoption.

This year i decided to host a number of hallway tracks, and also ran a beer and pizza meetup on the monday night prior to DockerCon.

Captains (b)Log – Part 2

As the open source core, Portainer CE remains very much a live project within the open source community. Since June 2018, the team has released versions 1.18.0 through 1.20.2 with a range of new features and capability. If you haven’t tried Portainer recently, here’s what you will find:

Using MACVLAN in

Pretty much everyone is comfortable with docker bridge networking, and probably even overlay networking, but how many have used Docker's MACVLAN network driver?
