Setup multiple git identities & git user informations

/!\ Be very carrefull in your setup : any misconfiguration make all the git config to fail silently ! Go trought this guide step by step and it should be fine 😉

Setup multiple git ssh identities for git

• Generate your SSH keys as per your git provider documentation.
• Add each public SSH keys to your git providers acounts.
• In your ~/.ssh/config, set each ssh key for each repository as in this exemple:

## USAGE
# $ nix-build kexec-installer.nix
# can be deployed remote like this
# $ rsync -aL -e ssh result/ root@host:
# $ ssh root@host ./kexec-installer
## Customize it like this
# # custom-installer.nix
# import ./kexec-installer.nix {
#   extraConfig = {pkgs, ... } {
#     user.extraUsers.root.openssh.authorizedKeys.keys = [ "<your-key>" ];

Verifying Amazon S3 multi-part uploads with the ETag hash

• https://savjee.be/2015/10/Verifying-Amazon-S3-multi-part-uploads-with-ETag-hash/

Uploading big files to Amazon S3 can be a bit of pain when you're on an unstable network connection. If an error occurs, your transfer will be cancelled and you can start the upload process all over again.

To check the integrity of a file that was uploaded in multiple parts, you can calculate the checksum of the local file and compare it with the checksum on S3. Problem is: Amazon doesn't use a regular md5 hash for multipart uploads. In this post we'll take a look at how you can compute the correct checksum on your computer so you can compare it to the checksum calculated by Amazon.

The solution So if you want to check if your files where transferred correctly, you have to compute the ETag hash in the same way that Amazon does. Luckily there is this bash script which splits up your files (like the multipart upload) and calculates the correct ETag hash.

• Example of sample Docker container setup with Chef - https://github.com/maxivak/template-docker-chef-provisioning

Chef provisioning

• Chef provisioning is a framework that allows clusters to be managed by the chef-client and the Chef server in the same way nodes are managed: with recipes.

• Chef provisioning is a collection of resources that enable the creation of machines and machine infrastructures using the chef-client.
