How to Reset a Git Branch
Use the following command to reset your local branch to match the remote branch (e.g., origin/main):
git reset --hard origin/main
Let us say you made changes remotely and now you need to match your current repo with updated one you will have to first fetch
git fetch
Then you will have to pull
git pull origin main
after doing these changes only you should be able to push new commits
How important is it to set password while creating deployment key for github private repository
Setting a password when creating a deployment key for a GitHub private repository is not just important—it 's critical for the security of your repository. Here 's why: ### **Importance of Password Protection:** 1. **Prevents Unauthorized Access:** - A deployment key is an SSH key that grants read or write access to your GitHub repository. If this key falls into the wrong hands, anyone could clone or modify your private codebase. Setting a password adds an extra layer of protection. 2. **Mitigates Security Risks:** - Without a password, if someone gains access to the deployment key, they can use it without any barriers. A password encrypts the key, meaning even if someone steals the key file, they can 't use it unless they also know the password. 3. **Compliance and Best Practices:** - Many organizations have security policies that require all sensitive credentials, including SSH keys, to be password-protected. Following these best practices ensures compliance with security standards. ### **Scenario Where Password Might Not Be Necessary:** - **Automated Systems:** - In cases where the key is used in an automated system (like a CI/CD pipeline) where human interaction is not possible or practical, a password might not be set. However, this increases the risk, and in such cases, other security measures should be in place, like IP whitelisting, monitoring, and regular key rotation. ### **Conclusion:** Setting a password on your deployment key is crucial unless there is a specific, controlled reason not to do so. It’s a simple step that significantly increases the security of your repository.
Will i need to enter password everytime i try to push anything in my repo
No, you won 't need to enter the password every time you push something to your repository if you configure SSH keys properly. Here 's how it works: ### **How SSH Keys Work with Passwords:** 1. **SSH Key without Password:** - If you don 't set a password when generating your SSH key, you 'll be able to push, pull, and perform other Git operations without being prompted for a password. 2. **SSH Key with Password:** - If you set a password on your SSH key, you 'll need to enter the password whenever the key is used for the first time in a session. This means: - **First Operation:** When you first push, pull, or clone using this key after opening a terminal session, you 'll be prompted to enter the password. - **Subsequent Operations:** In the same session, you typically won 't need to enter the password again because the key is cached in the SSH agent. ### **Using SSH Agent to Avoid Repeated Prompts:** - **SSH Agent:** - You can use an SSH agent to cache your password. The agent keeps the decrypted key in memory, so you only need to enter the password once per session. After that, the agent handles authentication, so you won 't be prompted for the password again until you restart your computer or close the terminal. - **Starting SSH Agent:** - On most systems, you can start the SSH agent and add your key like this: ```bash
eval "$(ssh-agent -s)" # Start the SSH agent ssh-add ~/.ssh/id_rsa # Add your SSH key to the agent
``` - After running this, you enter the password once, and the agent handles it for the rest of the session. ### **Conclusion:** If you set a password on your SSH key, you’ll need to enter it the first time you use the key in a session. However, by using an SSH agent, you can avoid being prompted multiple times. This setup balances security (by protecting your SSH key with a password) and convenience (by only needing to enter the password once per session).
