Bash SSH访问代码传递上的github repo

我试图从Codeship上的容器推送到github。在获得一个

权限被拒绝（publickey）

错误后，我遵循了以下建议：

我创建了一个名为publishto的服务，并通过一些步骤尝试重新创建文章的建议

My codeship_services.yml文件：

# codeship_services.yml
publish:
  build: 
    image: codeship/setting-ssh-key-test
    dockerfile: Dockerfile.publish
  encrypted_env_file: codeship.env.encrypted
  volumes:
    - ./.ssh:/root/.ssh

- name: temp publish service
  service: publish
  command: /bin/bash -c "echo -e $PRIVATE_SSH_KEY >> /root/.ssh/id_rsa"

- name: chmod id_rsa
  service: publish
  command: chmod 600 /root/.ssh/id_rsa

- name: add server to list of known hosts
  service: publish
  command: /bin/bash -c "ssh-keyscan -H github.com >> /root/.ssh/known_hosts"

- name: confirm ssh connection to server, authenticating with generated public ssh key
  service: publish
  command: /bin/bash -c "ssh -T git@github.com"

My codeship_steps.yml文件：

# codeship_services.yml
publish:
  build: 
    image: codeship/setting-ssh-key-test
    dockerfile: Dockerfile.publish
  encrypted_env_file: codeship.env.encrypted
  volumes:
    - ./.ssh:/root/.ssh

- name: temp publish service
  service: publish
  command: /bin/bash -c "echo -e $PRIVATE_SSH_KEY >> /root/.ssh/id_rsa"

- name: chmod id_rsa
  service: publish
  command: chmod 600 /root/.ssh/id_rsa

- name: add server to list of known hosts
  service: publish
  command: /bin/bash -c "ssh-keyscan -H github.com >> /root/.ssh/known_hosts"

- name: confirm ssh connection to server, authenticating with generated public ssh key
  service: publish
  command: /bin/bash -c "ssh -T git@github.com"

但是，在运行

jet步骤时，
权限被拒绝（公钥）

我已经按照文章中的说明生成了密钥，并将加密的私钥添加到
codeship.env.encryped

我缺少什么吗？
唯一缺少的步骤是注册

只有这样，使用相同公钥的SSH连接才有机会成功

如果没有，请至少尝试
ssh-Tvvgit@github.com
在最后一步中，为了获得更多线索。
谢谢@VonC！如果此回购协议是组织的一部分，则密钥是否在“部署密钥”下？我在组织的repo上看不到ssh密钥的位置。@泰勒：只要你的GitHub帐户是组织的一部分，你自己的帐户就足够了。
