Git Permission denied (publickey)

Create ssh_config with

Host git_hostname # probably bitbucket.org
  IdentityFile /d/ssh/id_rsa

It should be in ~/.ssh/config. You should be able to find out what configuration is your client reading when running ssh -vvv bitbucket.org.

It can also happen when u added SSH support in your repository. And can be fixed by following steps :

Use this command to create the SSH keys

ssh-keygen -t rsa -C "[email protected]"

Use this command to start your ssh-agent if it's not already running
```
eval `ssh-agent`
```
Then add your private key file to SSH
```
ssh-add ~/.ssh/<private_key_file>
```
Copy and paste your key in Bitbucket/ Github with
```
cat ~/.ssh/<public_key_file> | pbcopy
```
Sometime it does not persists between reboot. Then you have to add below lines in .ssh/config (For Mac)
```
Host *
    UseKeychain yes
    AddKeysToAgent yes
    IdentityFile ~/.ssh/<private_key_file>
```
