"Immersive terminal interface for managing docker containers and services

"

"A tool for exploring a docker image, layer contents, and discovering ways to shrink your Docker image size.

"kaniko is a tool to build container images from a Dockerfile, inside a container or Kubernetes cluster.

kaniko doesn't depend on a Docker daemon and executes each command within a Dockerfile completely in userspace. This enables building container images in environments that can't easily or securely run a Docker daemon, such as a standard Kubernetes cluster."

"Vitess is a database solution for deploying, scaling and managing large clusters of MySQL instances. It's architected to run as effectively in a public or private cloud architecture as it does on dedicated hardware. It combines and extends many important MySQL features with the scalability of a NoSQL database. Vitess can help you with the following problems:

Scaling a MySQL database by allowing you to shard it, while keeping application changes to a minimum.
Migrating from baremetal to a private or public cloud.
Deploying and managing a large number of MySQL instances.

Vitess includes compliant JDBC and Go database drivers using a native query protocol. Additionally, it implements the MySQL server protocol which is compatible with virtually any other language.

Vitess has been serving all YouTube database traffic since 2011, and has now been adopted by many enterprises for their production needs."

"PORTAINER IS AN OPEN-SOURCE LIGHTWEIGHT MANAGEMENT UI WHICH ALLOWS YOU TO EASILY MANAGE YOUR DOCKER HOSTS OR SWARM CLUSTERS

AVAILABLE ON LINUX, WINDOWS & OSX"

"container-diff is a tool for analyzing and comparing container images. container-diff can examine images along several different criteria, including:

Docker Image History Image file system Apt packages pip packages npm packages These analyses can be performed on a single image, or a diff can be performed on two images to compare. The tool can help users better understand what is changing inside their images, and give them a better look at what their images contain."

Kontena is an open source project for orchestrating and running containerized workloads on a cluster. Kontena system is comprised of a number of Kontena Nodes (machines or VMs that run containerized workloads) and a Kontena Master that controls and monitors the Nodes.

With Kontena, you can describe your application with Kontena Service definition. A Service definition describes the container image, networking, scaling and stateful/stateless attributes for your application. Services may be linked together to create desired architecture. Each service is automatically assigned with internal DNS address that can be used inside your application for inter-Service communications.

The summary of Kontena key features:

Scheduler with affinity filtering Built-in private Docker image registry Remote VPN access for workload services Ready made load-balancing service Log and statistics aggregation with streaming Access control and roles for Kontena users Kontena is used with Kontena command line interface Kontena CLI. At the moment, there is no graphical (web based) UI for Kontena.

"j2cli is a command-line tool for templating in shell-scripts, leveraging the Jinja2 library.

Features:

Jinja2 templating Allows to use environment variables! Hello Docker :) INI, YAML, JSON data sources supported"

"dumb-init is a simple process supervisor and init system designed to run as PID 1 inside minimal container environments (such as Docker). It is a deployed as a small, statically-linked binary written in C.

Lightweight containers have popularized the idea of running a single process or service without normal init systems like systemd or sysvinit. However, omitting an init system often leads to incorrect handling of processes and signals, and can result in problems such as containers which can't be gracefully stopped, or leaking containers which should have been destroyed.

dumb-init enables you to simply prefix your command with dumb-init. It acts as PID 1 and immediately spawns your command as a child process, taking care to properly handle and forward signals as they are received."

"A new, transactionally updated Ubuntu for clouds and devices.

Snappy Ubuntu Core is a new rendition of Ubuntu with transactional updates - a minimal server image with the same libraries as today’s Ubuntu, but applications are provided through a simpler mechanism. The snappy approach is faster, more reliable, and lets us provide stronger security guarantees for apps and users — that’s why we call them “snappy” applications."

"Flocker is a data volume manager and multi-host Docker cluster management tool. With it you can control your data using the same tools you use for your stateless applications. This means that you can run your databases, queues and key-value stores in Docker and move them around as easily as the rest of your app.

With Flocker's command line tools and a simple configuration language, you can deploy your Docker-based applications onto one or more hosts. Once deployed, your applications will have access to the volumes you have configured for them. Those volumes will follow your containers when you use Flocker to move them between different hosts in your Flocker cluster."

"It is a small tool allowing to enter into namespaces. Technically, it can enter existing namespaces, or spawn a process into a new set of namespaces. "What are those namespaces you're blabbering about?" We are talking about container namespaces.

nsenter can do many useful things, but the main reason why I'm so excited about it is because it lets you enter into a Docker container."
