Understanding Inner Loop Development and Pull Rates

We have heard feedback that given the changes Docker introduced relating to network egress and the number of pulls for free users, that there are questions around the best way to use Docker as part of your development workflow without hitting these limits. This blog post covers best practices that improve your experience and uses a sensible consumption of Docker which will mitigate the risk of hitting these limits and how to increase the limits depending on your use case. 

If you are interested in how these limits are addressed in a CI/CD pipeline, please have a look at our post: Best Practices for using Docker Hub for CI/CD. If you are using Github Action, have a look at our Docker Github Actions post.

Prerequisites

To complete this tutorial, you will need the following:

• Free Docker Account 
  • You can sign-up for a free Docker account and receive free unlimited public repositories
• Docker running locally
  • Instructions to download and install Docker
• An IDE or text editor to use for editing files. I would recommend VSCode

Determining Number of Pulls

ACI Fabric Access Policies Part 1: VLAN Pool

 

Introduction

 

Everything in ACI is managed as an Object. Each object belongs to a certain Class. As an example, when we create a VLAN Pool, we create an object that belongs to Class VlanInstP. Classes, in turn, are organized in Packages, Class VlanInstP belongs to Package fvns (fv = fabric virtualization, ns namespace). Figure 1-1 illustrates the classes that we are using in this chapter when we create Fabric Access Policies. Lines with an arrow represent Parent-Child structure and dotted lines represent a relationship (Rs) between classes. We will get back to Rs in becoming sections.

Docker and Snyk Extend Partnership to Docker Official and Certified Images

Today we are pleased to announce that Docker and Snyk have extended our existing partnership to bring vulnerability scanning to Docker Official and certified images. As the exclusive scanning partner for these two image categories, Snyk will work with Docker to provide developers with insights into our most popular images. It builds on our previous announcement earlier this year where Snyk scanning was integrated into the Docker Desktop and Docker Hub. This means that developers can now incorporate vulnerability assessment along each step of the container development and deployment process.

Docker Official images represent approximately 25% of all of the pull activity on Docker Hub. Docker Official images are used extensively by millions of developers and developer world wide teams to build and run tens of millions of containerized applications. By integrating vulnerability scanning from Snyk users are now able to get more visibility into the images and have a higher level of confidence that their applications are secure and ready for production.

Docker Official images that have been scanned by Snyk will be available early next year.

You can read more about it from Snyk here and you can catch Docker CEO Scott Johnson and Snyk CEO Peter McKay Continue reading

Dell launches Apex, a per-use hardware-leasing program

All of the major IT hardware suppliers to one degree or other have adopted a consumption model, which is a fancy word for leasing. Rather than the outright purchase of hardware, customers lease it, usage is monitored, and the customer pays a monthly use fee.Now Dell Technologies has announced it is expanding its as-a-service capabilities with Project APEX, to simplify how customers and partners access Dell technology on-demand.APEX will cover an array of Dell products —storage, servers, networking, hyperconverged infrastructure, PCs, and broader solutions. Project APEX will unify the company’s as-a-service and cloud strategies, technology offerings, and go-to-market efforts previously sold under the On Demand monicker.To read this article in full, please click here

The Cloudflare Radar 2020 Elections Dashboard

There is significant global attention around the upcoming United States election. Through the Athenian Project and Cloudflare for Campaigns, Cloudflare is providing free protection from cyber attacks to a significant number of state and local elections' websites, as well as those of federal campaigns.

One of the bedrocks of a democracy is that people need to be able to get access to relevant information to make a choice about the future of their country. This includes information about the candidates up for election; learning about how to register, and how to cast a vote; and obtaining accurate information on the results.

A question that I’ve been increasingly asked these past few months: are cyberattacks going to impact these resources leading up to and on election day?

Internally, we have been closely monitoring attacks on the broader elections and campaign websites and have a team standing by 24x7 to help our current customers as well as state and local governments and eligible political campaigns to protect them at no cost from any cyberattacks they may see.

The good news is that, so far, cyberattacks have not been impacting the websites of campaigns and elections officials we are monitoring and protecting. Continue reading

Validate Ansible YAML Data with JSON Schema

When I published the Optimize Network Data Models series a long while ago, someone made an interesting comment along the lines of “You should use JSON Schema to validate the data model.”

It took me ages to gather the willpower to tame that particular beast, but I finally got there. In the next installment of the Data Models saga I described how you can use JSON Schema to validate Ansible inventory data and your own YAML- or JSON-based data structures.
