CircleCI 2.0 - SSH 密钥丢失（从 Circle 1.0 迁移）

Question

从 Circle 1.0 迁移到 2.0。我可以毫无问题地获取我的代码，但是用于部署的 ssh 密钥似乎不可用。

关键在项目ssh权限

没有~/.ssh/config文件，密钥也不存在：

所以当部署步骤启动时，它失败了：

#!/bin/bash --login
if [ "${CIRCLE_BRANCH}" == "develop" ]; then
  bundle exec cap staging deploy
else
  echo "Not on develop branch"
fi

(Backtrace restricted to imported tasks)
cap aborted!
SSHKit::Runner::ExecuteError: Exception while executing as [redacted]@staging.captaincontrat.com: Authentication failed for user [redacted]@staging.captaincontrat.com

Net::SSH::AuthenticationFailed: Authentication failed for user [redacted]@staging.captaincontrat.com

Tasks: TOP => rvm:hook
(See full trace by running task with --trace)
Exited with code 1

我尝试使用 add_ssh_keys 步骤，但密钥仍然不可用。 As the documentation specifies that it adds all keys by default反正我删了

这是 config.yml 文件，其中大部分是迁移脚本的结果：

  build:
    working_directory: ~/captaincontrat/captaincontrat

    # So we need to use one with a large number of languages and other packages.

    # Deploy if develop
    #   This should be in a workflow, but workflows can't cancel redundant jobs for now.
    - deploy:
        name: Deploy to staging if branch is develop
        command: |
           if [ "${CIRCLE_BRANCH}" == "develop" ]; then
             bundle exec cap -t staging deploy

             echo "Not on develop branch => Not deploying to staging"
           fi
    # Teardown
    #   If you break your build into multiple jobs with workflows, you will probably want to do the parts of this that are relevant in each

我错过了什么‽ 谢谢！

编辑：这是解决方案

重点是：
- add_ssh_keys
- 然后 run evalssh-agent&& ssh-add ~/.ssh/id_rsa* 在 cap deploy 之前，因为我需要 .ssh/id_rsa 通过代理转发

检查代码库

# Deploy if develop
- add_ssh_keys
- deploy:
    name: Deploy to staging if branch is develop
    command: |
       if [ "${CIRCLE_BRANCH}" == "develop" ]; then
         eval `ssh-agent` && ssh-add ~/.ssh/id_rsa* && bundle exec cap staging deploy
  # ... snip

为确保代理转发，您可以在 capistrano 阶段配置中添加 set :ssh_options, forward_agent: true。

Answer 1

您需要执行 add_ssh_keys 步骤才能将 SSH 密钥注入容器。此步骤需要在 deploy 步骤之前。

当文档说默认添加所有键时，这意味着使用 add_ssh_keys 时。它说因为你也可以使用那个特殊的步骤来添加特定的键。
