A instead different occupation possibly, however I privation to specify a backstage SSH-cardinal to usage once executing a ammunition (git) bid from the section machine.
Fundamentally similar this:
git clone git@github.com:TheUser/TheProject.git -key "/home/christoffer/ssh_keys/theuser"Oregon equal amended (successful Ruby):
with_key("/home/christoffer/ssh_keys/theuser") do sh("git clone git@github.com:TheUser/TheProject.git")endI person seen examples of connecting to a distant server with Net::SSH that makes use of a specified backstage cardinal, however this is a section bid. Is it imaginable?
No of these options labored for maine.
Alternatively, I elaborate connected @Martin v. Löwis 's notation of mounting a config record for SSH.
SSH volition expression for the person's ~/.ssh/config record. I person excavation setup arsenic:
Host gitserv Hostname remote.server.com IdentityFile ~/.ssh/id_rsa.github IdentitiesOnly yes # see NOTES below AddKeysToAgent yesAnd I adhd a distant git repository:
git remote add origin git@gitserv:myrepo.git(oregon clone a caller transcript of the repo with git@gitserv:myrepo.git arsenic code)
And past git instructions activity usually for maine.
git push -v origin masterIf you person submodules, you tin besides execute the pursuing successful the repo listing, to unit the submodules to usage the aforesaid cardinal:
git config url.git@gitserv:.insteadOf https://remote.server.comNOTES
The
IdentitiesOnly yesis required to forestall the SSH default behaviour of sending the individuality record matching the default filename for all protocol. If you person a record named~/.ssh/id_rsathat volition acquire tried Earlier your~/.ssh/id_rsa.githubwith out this action.AddKeysToAgent yeslets you debar reentering the cardinal passphrase all clip.You tin besides adhd
User gitto debar penninggit@all clip.

Thing similar this ought to activity (urged by orip):
ssh-agent bash -c 'ssh-add /somewhere/yourkey; git clone git@github.com:user/project.git'if you like subshells, you might attempt the pursuing (although it is much fragile):
ssh-agent $(ssh-add /somewhere/yourkey; git clone git@github.com:user/project.git)Git volition invoke SSH which volition discovery its cause by situation adaptable; this volition, successful bend, person the cardinal loaded.
Alternatively, mounting HOME whitethorn besides bash the device, supplied you are consenting to setup a listing that accommodates lone a .ssh listing arsenic HOME; this whitethorn both incorporate an individuality.pub, oregon a config record mounting IdentityFile.
Once running with Git, particularly successful environments that necessitate unafraid authentication, specifying which SSH cardinal to usage for antithetic repositories oregon organizations turns into important. This ensures that the accurate individuality is utilized once interacting with distant servers, stopping approval errors and sustaining safety. Configuring SSH keys for circumstantial repositories permits you to negociate entree much effectively, particularly once dealing with aggregate initiatives all requiring antithetic ranges of entree power. This station volition usher you done the procedure of specifying the backstage SSH cardinal to usage once executing Git instructions, making certain seamless and unafraid interactions with your repositories.
Knowing SSH Cardinal Configuration for Git
SSH (Unafraid Ammunition) keys supply a unafraid manner to authenticate to distant servers with out needing to participate your password all clip. Successful a emblematic Git workflow, SSH keys are utilized to authenticate with companies similar GitHub, GitLab, oregon Bitbucket. Managing aggregate SSH keys, nevertheless, tin go analyzable. You mightiness person 1 cardinal for individual initiatives and different for activity-associated repositories. Git, mixed with SSH configuration, permits you to specify which cardinal to usage for which repository, streamlining the authentication procedure. This ensures that once you propulsion, propulsion, oregon execute another Git operations, the accurate cardinal is offered to the distant server.
However to Specify an SSH Cardinal for a Circumstantial Git Repository
Specifying an SSH cardinal for a circumstantial Git repository includes configuring your SSH case to usage the due cardinal based mostly connected the hostname oregon repository URL. The capital technique for this is done the SSH configuration record, sometimes situated astatine ~/.ssh/config. This record permits you to specify settings for antithetic hosts, together with which individuality record (backstage cardinal) to usage. By mounting ahead these configurations, you tin guarantee that Git makes use of the accurate SSH cardinal mechanically once interacting with antithetic repositories. This attack is peculiarly utile once you person aggregate GitHub accounts, all related with a antithetic SSH cardinal, oregon once accessing repositories hosted connected antithetic platforms that all necessitate alone authentication.
To configure your SSH case, you’ll demand to edit the ~/.ssh/config record. If the record doesn't be, you tin make it. Present’s a measure-by-measure usher:
- Unfastened the SSH configuration record: Usage a matter application to unfastened ~/.ssh/config.
- Adhd a adult configuration: For all repository oregon adult, adhd a conception similar the pursuing:
Host github.com-personal HostName github.com User git IdentityFile ~/.ssh/id_rsa_personal Successful this illustration:
Host github.com-personal: This is an alias you make. It doesn’t person to lucifer the existent hostname however ought to beryllium descriptive.HostName github.com: This is the existent hostname of the Git server.User git: This is the person that SSH volition effort to log successful arsenic. For about Git companies, this is git.IdentityFile ~/.ssh/id_rsa_personal: This specifies the way to the backstage cardinal you privation to usage for this adult.
Brand certain to set the paths and hostnames to lucifer your circumstantial setup. Last configuring the SSH config record, replace the Git distant URL for your repository to usage the alias you created. For illustration, alternatively of:
git@github.com:username/repository.git Usage:
git@github.com-personal:username/repository.git Present, once you tally Git instructions for this repository, it volition mechanically usage the specified SSH cardinal.
Alternate Strategies for Specifying SSH Cardinal Utilization successful Git
Piece configuring the SSH config record is the about communal and advisable technique, location are alternate methods to specify SSH cardinal utilization successful Git. These strategies mightiness beryllium utile successful circumstantial situations oregon once you demand a speedy resolution with out modifying your SSH configuration. 1 specified technique includes utilizing the GIT_SSH_COMMAND situation adaptable. This adaptable permits you to specify a customized SSH bid to beryllium utilized by Git, which tin see choices to specify the individuality record straight. Wherefore ought to I utilization a pointer alternatively than the entity itself? Moreover, any Git shoppers oregon GUI instruments whitethorn supply their ain settings for managing SSH keys, providing a person-affable interface for specifying which cardinal to usage for antithetic repositories. Nevertheless, these strategies mightiness not beryllium arsenic versatile oregon dependable arsenic configuring the SSH config record, particularly once dealing with analyzable setups.
Present's however you tin usage the GIT_SSH_COMMAND situation adaptable:
GIT_SSH_COMMAND="ssh -i ~/.ssh/id_rsa_specific" git clone git@github.com:username/repository.git Successful this illustration, the GIT_SSH_COMMAND is fit to usage the ssh bid with the -i action to specify the individuality record (~/.ssh/id_rsa_specific). This bid is past utilized for the git clone cognition. This technique is utile for 1-disconnected instructions however tin go cumbersome for daily usage. To brand it much imperishable for a circumstantial repository, you tin fit the situation adaptable successful your ammunition's configuration record (e.g., .bashrc oregon .zshrc).
