DSB Social Network - Transition and Tuning Guide

Step 1: Download all the original AMD64 tar.gz packages from Stacksmith repository of Bitnami. URL is in Appendix A

• MongoDB Shell
• MongoDB Server
• MongoDB Exporter
• Yq
• Wait-for-port
• Render-template
• Gosu
• Memcached
• Memcached-Exporter
• Redis
• Redis-exporter

Step 2: Download ARM64 binaries that correspond to above AMD64 packages

• MongoDB Shell
• MongoDB Server (Refer Appendix B for instructions to extract deb packages)
• MongoDB Exporter (Prometheus)
• MongoDB Tools (mongodb- exporter)
• Yq
• Wait-for-port
• Render-template
• Gosu
• Memcached_exporter
• Redis-exporter (oliver006 repository on github)

Please note the package ‘mongoexport’ and the package ‘mongodb-exporter’ are two different utilities. The mongodb-exporter is from ‘percona’ and the other is from ‘mongodb database tools’.

• Build ARM64 binaries from source for the below packages (Check for exact file name before replacing with amd64 equivalent binary)

Step 3: Build ARM64 binaries from source for the below packages (Check for exact file name before replacing with amd64 equivalent binary)

• memcached
• redis-server
• kubectl

Step 4:

• Extract the AMD64 packages that were downloaded in Step 1, and then one by one copy/replace only the amd64 binary with the arm64 binary (downloaded/built in Step 2) keeping the folder structure of above packages intact.
  • For example, the folder structure of MongoDB shell AMD64 package is as below,

• Inside the bin folder, delete AMD64 binary ‘mongosh’ and copy ARM64 binary ‘mongosh’ in its place. No other folder structure changes or files need to be modified.
• Once the ARM64 binary is copied, then rename the folder name part of ‘amd64’ with ‘arm64’ and finally compress the folder again into tar.gz format

Step 5: Repeat the above Steps 4 until:

• All AMD64 packages have been extracted.
• All corresponding ARM64 binaries copied to ‘bin’ folders and,
• All folders containing ARM64 binaries are re-named and re-compressed again into tar.gz packages

Step 6:

• Copy/Move the packages to a static location like S3 bucket in AWS or other repository as per availability. Please check the example image below.
• Provide appropriate access to the files so that docker can fetch these during build process
