Accessing the Docker Daemon via an SSH Bastion Host

Today I came across this article, which informed me that (as of the 18.09 release) you can use SSH to connect to a Docker daemon remotely. That’s handy! The article uses docker-machine (a useful but underrated tool, I think) to demonstrate, but the first question in my mind was this: can I do this through an SSH bastion host? Read on for the answer.

If you’re not familiar with the concept of an SSH bastion host, it is a (typically hardened) host through which you, as a user, would proxy your SSH connections to other hosts. For example, you may have a bunch of EC2 instances in an AWS VPC that do not have public IP addresses. (That’s reasonable.) You could use an SSH bastion host—which would require a public IP address—to enable SSH access to otherwise inaccessible hosts. I wrote a post about using SSH bastion hosts back in 2015; give that post a read for more details.

The syntax for connecting to a Docker daemon via SSH looks something like this:

docker -H ssh://user@host <command>

So, if you wanted to run docker container ls to list the containers running on a remote system, you’d Continue reading

BiB 081: 128 Technology Rethinks The WAN Router

128 Technology takes an interesting approach to WAN routing. In this Brief Briefing Ethan Banks and Drew Conry-Murray skim the surface of 128 Technology's approach, which includes stateful sessions, NAT, and encryption--but no tunneling. We also touch on use cases including SD-WAN and security. We also provide links to Networking Field Day videos that have much more detail.

Self-organizing micro robots may soon swarm the industrial IoT

Miniscule robots that can jump and crawl could soon be added to the industrial internet of things’ arsenal. The devices, a kind of printed circuit board with leg-like appendages, wouldn’t need wide networks to function but would self-organize and communicate efficiently, mainly with one another.Breakthrough inventions announced recently make the likelihood of these ant-like helpers a real possibility.[ Also see: What is edge computing? and How edge networking and IoT will reshape data centers ] Vibration-powered micro robots The first invention is the ability to harness vibration from ultrasound and other sources, such as piezoelectric actuators, to get micro robots to respond to commands. The piezoelectric effect is when some kinds of materials generate an electrical charge in response to mechanical stresses.To read this article in full, please click here

Extend CI/CD with CR for Continuous App Resilience

This is a guest post written by Govind Rangasamy, CEO and Founder, Appranix.

The radical shift towards DevOps and the continuous everything movement have changed how organizations develop and deploy software. As the consolidation and standardization of continuous integration and continuous delivery (CI/CD) processes and tools occur in the enterprise, a standardized DevOps model helps organizations deliver faster software functionality at a large scale. However, newer cyber threats, evolving regulatory requirements, and the need to protect brand reputation are putting tremendous pressure on IT leaders to effectively protect their customer and business-critical data.

Conceptually, DevOps pipeline approach makes a lot of sense, however, in practice, Site Reliability Engineering (SRE) and Ops teams optimize systems for service reliability and robustness at the cost of delivering new features. The need for software reliability inherently decreases Continuous Delivery (CD) throughput. This conundrum is the biggest challenge for any organization adopting DevOps practices at a large scale today. By integrating and extending CI/CD with Continuous Resilience (CR) to provide protection against multitudes of software reliability disruptions, DevOps teams can confidently deploy new software and not affect resiliency of the systems. In other words, Continuous Resilience is the radical new enabler that gives confidence for Continue reading

Asia-Pacific ICT Ministers Focus on Co-Creating the Future of the Internet

Last month, ICT ministers across Asia-Pacific got together in Singapore to decide on the direction of ICT development in the region. At the end of the three-day gathering, leaders adopted the Singapore Statement of the Asia-Pacific ICT Ministers on Co-creating a Connected Digital Future in the Asia-Pacific, a set of high-level policy guidelines that will set the tone for activities of the Asia-Pacific Telecommunity (APT) in the next five years. 
The Singapore Statement is significant in that it fortifies the principles that underpin a conducive environment for the digital economy to thrive:

• It reinforces support for the multistakeholder approach, with states highlighting their own efforts to make ICT policy processes more inclusive during the meeting.
• It renews its commitment to foster digital communities through collaborative projects to connect unserved and underserved areas.
• It makes explicit references to interoperability and the free and secure flow of information online, putting equal weight on protecting users’ privacy.

It is particularly encouraging to see that amidst the race to capitalize on the vast amounts of data collected from us and our online activities, ICT Ministers opted to focus on trust –  built on accountability, transparency, and ethics – as a fundamental pillar in the Continue reading

Kubernetes Operators with Ansible Deep Dive: Part 2

In part 1 of this series, we looked at operators overall, and what they do in OpenShift/Kubernetes. We peeked at the Operator SDK, and why you'd want to use an Ansible Operator rather than other kinds of operators provided by the SDK. We also explored how Ansible Operators are structured and the relevant files created by the Operator SDK when building Kubernetes Operators with Ansible.

In this the second part of this deep dive series, we'll:

1. Take a look at creating an OpenShift Project and deploying a Galera Operator
2. Next we’ll check the MySQL cluster, then setup and test a Galera cluster
3. Then we’ll test scaling down, disaster recovery, and demonstrate cleaning up

Creating the project and deploying the operator

We start by creating a new project in OpenShift, which we'll simply call test:

$ oc new-project test --display-name="Testing Ansible Operator"
Now using project "test" on server "https://ec2-xx-yy-zz-1.us-east-2.compute.amazonaws.com:8443".

We won't delve too much into this role, however the basic operation is:

1. Use set_fact to generate variables using the k8s lookup plugin or other variables defined in defaults/main.yml.
2. Determine if any corrective action needs to be taken based on the above variables. For example, one Continue reading
