This document contains Matthew Shellhart's student ID number COMP001020240451, the date of August 22, 2013, and what appears to be a randomly generated string of characters, L00QXRLL7HQQ2KMD, likely used for authentication purposes.
This document provides an introduction to Docker and includes instructions for several exercises to help users learn Docker in 90 minutes. The document covers downloading and running Docker containers, creating Docker images, understanding Docker layers, exposing container ports, using Dockerfiles to build images, and sharing images in Docker repositories. The exercises guide users through hands-on experience with common Docker commands and concepts.
Shipping Applications to Production in Containers with DockerJérôme Petazzoni
This document provides an overview and introduction to using Docker in production environments. It discusses how Docker can help with "solved" problems like installing, building, and distributing applications. It also covers important areas for production Docker usage, such as service discovery, orchestration, performance, configuration management, and sysadmin tasks. The document outlines various approaches in each area and notes that there are often multiple valid solutions to consider.
A Gentle Introduction To Docker And All Things ContainersJérôme Petazzoni
Docker is a runtime for Linux Containers. It enables "separation of concern" between devs and ops, and solves the "matrix from hell" of software deployment. This presentation explains it all! It also explains the role of the storage backend and compares the various backends available. It gives multiple recipes to build Docker images, including integration with configuration management software like Chef, Puppet, Salt, Ansible. If you already watched other Docker presentations, this is an actualized version (as of mid-November 2013) of the thing!
Configuration management tools like Chef, Puppet, and Ansible aim to reduce inconsistencies by imposing and managing consistent configurations across environments. However, they do not fully address issues related to dependencies, isolation, and portability. Docker containers build on these tools by adding standard interfaces and a lightweight virtualization layer that encapsulates code and dependencies, allowing applications and their environments to be packaged together and run consistently on any infrastructure while also providing isolation.
Docker is a system for running applications in isolated containers. It addresses issues with traditional virtual machines by providing lightweight containers that share resources and allow applications to run consistently across different environments. Docker eliminates inconsistencies in development, testing and production environments. It allows applications and their dependencies to be packaged into a standardized unit called a container that can run on any Linux server. This makes applications highly portable and improves efficiency across the entire development lifecycle.
Docker from A to Z, including Swarm and OCCSFrank Munz
This document provides an overview of Docker from A to Z including using Docker with Oracle Container Cloud Service. It discusses basics of Docker including how it provides isolation using Linux namespaces and cgroups. It compares Docker containers to virtual machines and covers Docker images, containers, limitations, networking, security concerns and suggestions. It also discusses using Docker with Oracle technologies including Dockerfiles on GitHub, the Oracle Container Registry, and Oracle Container Cloud Service.
Study: The Future of VR, AR and Self-Driving CarsLinkedIn
We asked LinkedIn members worldwide about their levels of interest in the latest wave of technology: whether they’re using wearables, and whether they intend to buy self-driving cars and VR headsets as they become available. We asked them too about their attitudes to technology and to the growing role of Artificial Intelligence (AI) in the devices that they use. The answers were fascinating – and in many cases, surprising.
This SlideShare explores the full results of this study, including detailed market-by-market breakdowns of intention levels for each technology – and how attitudes change with age, location and seniority level. If you’re marketing a tech brand – or planning to use VR and wearables to reach a professional audience – then these are insights you won’t want to miss.

What does the future look like? Is it a dark space where we’re suffering from varying degrees of techamphetamine or are we heading towards a Utopian fantasy of abundance and harmony?
Understanding that our basic human needs and wants barely change, we explore the future state of a range of topics; from our need for physical sustenance through to our age-long fascination of transcending the limitations of our biology.
Looking at the future from a human perspective, our potential for greatness is teetering on a fine line between darkness and hope. We’re banking on the latter.
2. Application on Web
● Using Web as User Interface
● Example
– Database : phpmyadmin
● php, mysql
– Mail : web mail
● roundcube
● squirrelmail
– Weblog – blog
● wordpress
3. phpmyadmin
● ติดตั้ง
$ sudo apt-get install phpmyadmin
● config
– เลือก apache2 เป็ น Web Server
– admin password สำำหรับ mysql server (root)
– password สำำหรับ phpmyadmin
● LEAVE IT BLANK (phpmyadmin จะ gen random password ให้)
9. ปั ญหำของ DNS
$ host t a www.domain.com localhost
● ถ้ำไม่สำมำรถ resolve ได้แสดงว่ำ named server บน
VM มีปัญหำ
● ตรวจสอบว่ำ named run อย่่หรือเปล่ำ?
$ ps auxw | grep named
● ถ้ำไม่มีให้ start bind9
$ sudo service bind9 start
11. ปั ญหำของ DNS (ต่อ)
$ host t a www.domain.com 172.30.0.85
$ host t a www.domain.com lsasvr.coe.psu.ac.th
● ถ้ำไม่สำมำรถ resolve ได้แสดงว่ำ ข้อม่ลของ zone มีปัญหำ
● ใน zone ไฟล์ /var/cache/bind/master/domain.com จะต้องมี
– record ของ NS 2 record
$ORIGIN domain.com.
IN NS lsasvr.coe.psu.ac.th.
IN NS ns.domain.com.
– Note: บรรทัด $ORIGIN มีควำมสำำคัญ
– และมี A record ของ ns.domain.com ซึ่งมี IP Address เป็ นของ VM ในขณะนี้
ns IN A 172.30.160.xx
12. ปั ญหำของ DNS (ต่อ)
● ทุกครั้งที่แก้ไข zone ไฟล์ ให้ update serial
ของ SOA เสมอ
● หลังจำกแก้ไขเสร็จ reload config แล้ว
ตรวจสอบอีกครั้ง
● ถ้ำยังใช้งำนไม่ได้ → ยกมือถำม
22. เพิ่ม name ต่อไปนี้ใน Zone file
●
shell
●
webmail
● pma (phpmyadmin)
●
webmin
●
blog
pma IN A 172.30.160.xxx
shell IN A 172.30.160.xxx
...
● เพื่อให้สำมำรถใช้ช่ อ pma.domain.com (และอื่ นๆ) ได้
