Docker allows users to run applications in isolated containers using images from a registry similar to an app store. It simplifies deploying applications by allowing them to run without installing dependencies on the host machine. The docker architecture includes a client, host with docker daemon, images used to create containers which run applications, and a registry to store images. Users can install docker, search for images, run containers from images, check running containers, kill containers, and share data between containers and hosts.

Containers and docker
Containers and dockerSUDIP GHOSH Docker allows users to run isolated processes called containers. Containers leverage features of the host operating system like namespaces and cgroups to isolate resources and run multiple containers on a single host. Docker uses images which are read-only templates used to create containers. Images are composed of layered filesystems. The Dockerfile defines how to build an image. Docker provides tools to manage the entire container lifecycle from image management to container runs. It standardizes the package and distribution of applications as container images. This helped drive adoption of containers and microservices architectures in DevOps workflows.
Docker basics
Docker basicsAmanSoni129 Docker allows packaging applications and dependencies into containers to ensure applications work seamlessly across environments. Docker images are blueprints used to create containers, which are runnable instances of images. Dockerization is useful for standardizing environments and ensuring applications run the same on different machines through containerization. The document demonstrates creating an MSSQL server Linux container using Docker by running a command to specify environment variables and port mapping.

Docker uses images to build containers, which are isolated environments that run applications. A Dockerfile defines commands to build an image. Docker Hub is a registry that stores public and private images. Common commands include build to create images, run to launch containers, and push/pull to share images.

How Valletta helped healthcare SaaS to transform QA and compliance to grow wi...
How Valletta helped healthcare SaaS to transform QA and compliance to grow wi...Egor Kaleynik This case study explores how we partnered with a mid-sized U.S. healthcare SaaS provider to help them scale from a successful pilot phase to supporting over 10,000 users—while meeting strict HIPAA compliance requirements.
Faced with slow, manual testing cycles, frequent regression bugs, and looming audit risks, their growth was at risk. Their existing QA processes couldn’t keep up with the complexity of real-time biometric data handling, and earlier automation attempts had failed due to unreliable tools and fragmented workflows.
We stepped in to deliver a full QA and DevOps transformation. Our team replaced their fragile legacy tests with Testim’s self-healing automation, integrated Postman and OWASP ZAP into Jenkins pipelines for continuous API and security validation, and leveraged AWS Device Farm for real-device, region-specific compliance testing. Custom deployment scripts gave them control over rollouts without relying on heavy CI/CD infrastructure.
The result? Test cycle times were reduced from 3 days to just 8 hours, regression bugs dropped by 40%, and they passed their first HIPAA audit without issue—unlocking faster contract signings and enabling them to expand confidently. More than just a technical upgrade, this project embedded compliance into every phase of development, proving that SaaS providers in regulated industries can scale fast and stay secure.

Who Watches the Watchmen (SciFiDevCon 2025)
Who Watches the Watchmen (SciFiDevCon 2025)Allon Mureinik Tests, especially unit tests, are the developers’ superheroes. They allow us to mess around with our code and keep us safe.
We often trust them with the safety of our codebase, but how do we know that we should? How do we know that this trust is well-deserved?
Enter mutation testing – by intentionally injecting harmful mutations into our code and seeing if they are caught by the tests, we can evaluate the quality of the safety net they provide. By watching the watchmen, we can make sure our tests really protect us, and we aren’t just green-washing our IDEs to a false sense of security.

- 5. 3. Playing with docker ● Installing docker ( Cenos ) https://github.com/miendinh/docker-notes/blob/master/centos-install.md ● Other OS https://docs.docker.com/engine/installation/ ● User search “an app” ( image ) ○ docker search <image-name>[:<tag>] Ex: docker search ubuntu ● Setup “app” ( to create container ) Ex: docker run -ti ubuntu:14.02
