gitpod + commit with no reply email

amogh2019 — Mon, 20 Mar 2023 12:47:31 +0000

Problem :
Were not able to push commits from gitpod since i enabled email privacy in github, and gitpod was pushing commits with my private email.

Soln :
As mentioned on their account page

You can override Git author name and email per project by using the default environment variables GIT_AUTHOR_NAME, GIT_COMMITTER_NAME, GIT_AUTHOR_EMAIL and GIT_COMMITTER_EMAIL.

upon setting both

GIT_AUTHOR_EMAIL and GIT_COMMITTER_EMAIL to the your_no_reply_email_which_looks_like_username@users.noreply.github.com commits were finally pushed with correct no reply email.

gpg signing is still not solved. to-be-done later

setting up code editors on my machine

for java

sdk list java // to check which java version you want
sdk install java 19-open

install vscode // intellij

sudo snap install intellij-idea-community --classic
sudo snap install code --classic

vscode
// enable File>Autosave
// add gitlens

intellij community
// add sonarlint // for java

check and make a sample commit in a repo and push // check the push is as desired
checkout a sample repo

setting gitconfig

setting up my github username as name

git config --global user.name "nameorusername"

setting up my private no reply email as my email

git config --global user.email "youremail/noreplygithubemail"

telling git to use my gpg key, present on this computer and which is already added to my github account (check part 2 of this series) and always sign by default

git config --global user.signingkey {{keyidinlongformat}}
git config --global commit.gpgsign true

do a commit // check git log // check the latest commit // name and email is what you want, right?
push on github // check commit is verified green

GPG keys to display your commits with green tick!

Ref : https://docs.github.com/en/authentication/managing-commit-signature-verification

Managing commit signature verification
GitHub will verify GPG, SSH, or S/MIME signatures so other people will know that your commits come from a trusted source. GitHub will automatically sign commits you make using the GitHub web interface.

considering setup is from scratch

$ gpg --full-generate-key
4096 length // 0 for no expiry // some passphrase
add your github account email only // use the no reply email if you are keeping email private
once generated, test if key is present // gpg --list-secret-keys --keyid-format=long
get the actual key using key id (from the above listing) // gpg --armor --export thekeyid(look for sec rsa4096/{id})
Copy your GPG key, beginning with -----BEGIN PGP PUBLIC KEY BLOCK----- and ending with -----END PGP PUBLIC KEY BLOCK-----.
add to github>settings>access>GPG key
tell git on local machine to sign commits using the gpg key created above // follow in 3rd part of this series i.e. next article

If GPG commit fails

could be because gpg was password protected
just run: echo "test" | gpg --clearsign
this would prompt for gpg password (and save in shell i guess)...such that later it doesnt prompt

SSH connection to Github

amogh2019 — Sun, 27 Nov 2022 07:28:55 +0000

from my new machine, wanted to checkout my existing github repo and start making commits.

how do I do connect to it via SSH?
for ssh we would need a private and public key pair,
private key we keep, and public key we let github know.

lets do this

setting this up on ubuntu / linux

assuming no existing key is present // generate ssh keypair

$ ssh-keygen -t ed25519 -C "your_email@example.com or username"

add private key to ssh-agent // why??

$ ssh-add ~/.ssh/id_ed25519

copy public key and add to github account (settings>access>ssh keys)

public key details is here
$ cat ~/.ssh/id_ed25519.pub
  # Then select and copy the contents of the id_ed25519.pub file
  # displayed in the terminal to your clipboard

test ssh connection from terminal

$ ssh -T git@github.com
