Can't access AWS CodeCommit with SSH

问题

Having an incredibly difficult time figuring out how to get AWS CodeCommit to work with standard SSH authentication. Seen another topic like this but no answer and I'm not allowed to comment yet. This is on Windows using Git Bash.

Repro Steps

Created IAM user with full permissions (AwsAdministrator)
From Git Bash in ~/.ssh
"cat id_rsa.pub" and copy output to clipboard
In IAM console, click button to add SSH key and paste into the input field. Click Save.
Attempt to access a CodeCommit repo (in this case trying to push) and get "Permission denied".

Git + SSH output

This is what I get from SSH with DEBUG3 logging:

debug3: authmethod_is_enabled publickey
debug1: Next authentication method: publickey
debug1: Offering RSA public key: /c/Users/Dan/.ssh/id_rsa
debug3: send_pubkey_test
debug2: we sent a publickey packet, wait for reply
debug1: Server accepts key: pkalg ssh-rsa blen 535
debug2: input_userauth_pk_ok: fp SHA256:<omitted>
debug3: sign_and_send_pubkey: RSA SHA256:<same-as-above>
debug1: Authentications that can continue: publickey
debug2: we did not send a packet, disable method
debug1: No more authentication methods to try.
Permission denied (publickey).
fatal: Could not read from remote repository.

For comparison this is what I get using the exact same SSH keys to GitHub:

debug3: authmethod_is_enabled publickey
debug1: Next authentication method: publickey
debug1: Offering RSA public key: /c/Users/Dan/.ssh/id_rsa
debug3: send_pubkey_test
debug2: we sent a publickey packet, wait for reply
debug1: Server accepts key: pkalg ssh-rsa blen 535
debug2: input_userauth_pk_ok: fp SHA256:<same-as-above>
debug3: sign_and_send_pubkey: RSA SHA256:<same-as-above>
debug1: Authentication succeeded (publickey).
Authenticated to github.com ([192.30.252.130]:22).

The above output was from running a normal git command such as git push origin master with ssh debug logging enabled in .ssh/config:

Host git-codecommit.us-east-1.amazonaws.com
  LogLevel DEBUG3

Host github.com
  LogLevel DEBUG3

回答1:

It looks like you missed a step in setting up SSH. You need to add this information to your .ssh/config file:

Host git-codecommit.us-east-1.amazonaws.com
   User Your-SSH-Key-ID, such as APKAEIBAERJR2EXAMPLE
   IdentityFile Your-Private-Key-File, such as ~/.ssh/codecommit_rsa or ~/.ssh/id_rsa

You can get Your-SSH-Key-ID from the IAM console.

My case was a bit different.

The "Security credentials" tab has both "Access keys" and "SSH keys for AWS CodeCommit". Make sure you're using the CodeCommit key id.
