我已经设置了 jenkins，现在我想将节点添加到 jenkins，我按照以下步骤操作如何连接远程 SSH 从属设备。
有一个使用slave node私钥创建凭证的步骤。我尝试使用 ansible 的 jenkins api 创建该凭证。
剧本中的任务包括
- name: Read private key file content of slave1
slurp:
src: "{{ ansible_env.HOME }}/.ssh/slave1"
register: private_key_file
tags:
- credential
- name: Add credential to add node
uri:
body: |
json={
"": "0",
"credentials": {
"scope": "GLOBAL",
"id": "jenkins_linux_slave1_auth",
"username": "jenkins",
"password": "",
"privateKeySource": {
"stapler-class": "com.cloudbees.jenkins.plugins.sshcredentials.impl.BasicSSHUserPrivateKey$DirectEntryPrivateKeySource",
"privateKey": "{{ private_key_file['content'] | b64decode }}",
},
"description": "Jenkins Linux Slave1 Authentication",
"stapler-class": "com.cloudbees.jenkins.plugins.sshcredentials.impl.BasicSSHUserPrivateKey"
}
}
force_basic_auth: yes
method: POST
password: "{{ jenkins_user_token }}"
status_code: 302
url: "{{ jenkins_url }}/credentials/store/system/domain/_/createCredentials"
user: "{{ jenkins_user }}"
validate_certs: no
tags:
- credential
但这失败了，因为
$ ansible-playbook -i hosts jenkins_config.yaml --verbose -u root --ask-pass -b -e "jenkins_user=admin" -e "jenkins_user_token=admin" --tags credential
Using /root/ansible_playbooks/ansible.cfg as config file
SSH password:

如果我将私人文件的内容手动复制到privateKey有效载荷中，它可以正常工作。
复制文件内容 和 有什么区别slurp['content]|b64decode？
答案1
我认为您的 JSON 在模板引擎扩展后无效。JSON 文件中的字符串可能不包含换行符，而您的私钥字符串包含换行符。您可以使用以下工具验证您的 JSON：JSONLint。
答案2
用于sed -e 's/\n/\\n/g' privkey.rsa更改你的私钥，并且可以对其进行解析
