Kong docker container exits with 132 error code without any message

Docker Container Exited (132)

I was building entire Devops environment with ansible automation and suddenly Kong stack didn't start properly.

 The problem was that the Dev server was old Dell Server and it doesn't support "sse4_2" feature from CPU.

What is SSE Technology?

SSE is a processor technology that enables single instruction multiple data. ... SSE is designed to replace MMX™ Technology. It expanded over the generations of Intel® Processors to include SSE2, SSE3/SSE3S, and SSE4. Each iteration has brought new instructions and increased performance.

Information from CPUInfo


 [root@dockerdv01 ~]# cat /proc/cpuinfo | grep sse4_
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts mmx fxsr sse sse2 ss syscall nx rdtscp lm constant_tsc arch_perfmon pebs bts nopl xtopology tsc_reliable nonstop_tsc aperfmperf pni pclmulqdq ssse3 cx16 sse4_1 sse4_2 x2apic popcnt tsc_deadline_timer aes hypervisor lahf_lm tsc_adjust dtherm ida arat
[root@dockerdv01 ~]#

Old Dell Server supports only sse_4_1 and this was the issue. After moving to new server which supports sse4_2, Kong deploys properly

Replacing text in PDF file using iTextSharp

ReplacingTextUsingITextSharp title: Replacing text in PDF file using iTextSharp tags: - PDF - Replace Text - iTextSharp date: Nov 11, 2016 Overview I’ve trying to replace text in PDF file and this is most simple way to replace text in PDF files. Before approaching this, I’ve tried to replace text using command toolkit with pdftk, qpdf to decrypt, and sfk181 to replace string with new, but this approach faced couple of issues; 1. font, 2. text area size. After long investigation, this may be easy way to replace text. Put white colored rectangle on top of string and stamp text on the location like erase text using whitner and write on top of it.

Using GIT(Bitbucket), Visual Studio Code

Concept of Git Git has two repositories; local and remote. Two different commands type to commit the changes; 1. commit/add: load/save changes to the local repository. 2. push/pull/clone: load/save changes from/to remote repository. How to setup remote git server , bitbucket , with Visual Studio Code To use git, I downloaded it from [git-scm](“ https://git-scm.com/downloads “) and installed with bash mode to keep the comparability for different platform. Set up remote repository * Create project from bitbucket. In this case, I created “blogmarkdown”. Remember the URL for the git repository. To find out the repository, just add “.git” at the end of the URL from bitbucket. For me, it will be “ https://alexjoh@bitbucket.org/alexjoh/blogmarkdown.git ” Link the remote with local folder * Create local folder. In my case, I created d:\gitrepo Initialize git local repo. Change the folder to the gitrepo and run git init If there are existing files from a remote git re...
