gitlab CI：加载密钥时出错：格式无效

Question

我被困在这个问题上 2 天了。

从我的生产服务器尝试使用 id_rsa.pub 和 id_rsa，仍然是同样的错误...... SSH_PRIVATE_KEY 是我在 GitLab 的 CI/CD 设置中创建的变量。

当我运行管道时，我仍然收到此错误...

$ echo "$SSH_PRIVATE_KEY" | ssh-add -
Error loading key "(stdin)": invalid format

能否请你帮忙 ？我很无助，无能为力，无望加载...

非常感谢 ！

SSH_PRIVATE_KEY 是我在 GitLab 的 CI/CD 设置中创建的变量。

这是记录在这里

在值字段中粘贴您之前创建的私钥的内容。

因此，请确保您已粘贴id_rsa完整内容，包括-----BEGIN RSA PRIVATE KEY-----和-----END RSA PRIVATE KEY-----（带有 5 个 final -）
（并且，正如MrDuk 评论的那样，最后一个换行符）

Stephane Paquet在评论中补充道：

cat ~/.ssh/id_rsa | pbcopy 

以确保您复制了所有必需的信息。
