使用Ansible，请告知我如何从Github存储库下载最新版本的二进制文件。根据我目前的理解，这些步骤将是： 一种。获取最新版本的URL b。下载版本
我有类似的东西不能提供实际的版本（例如v0.11.53）：
- name: get latest Gogs release
local_action:
module: uri
url: https://github.com/gogits/gogs/releases/latest
method: GET
follow_redirects: no
status_code: 301
register: release_url
对于b。我有下面的工作，但需要不断更新。而不是版本，我需要在a。：
中设置一个变量- name: download latest
become: yes
become-user: "{{gogs_user}}"
get_url:
url: https://github.com/gogs/gogs/releases/download/v0.11.53/linux_amd64.tar.gz
dest: "/home/{{gogs_user}}/linux_amd64.tar.gz"
谢谢！

Github具有一个documented发行版的API。
因此，假设您想获得最新版本的ansible（属于ansible项目）
https://api.github.com/repos/ansible/ansible/releases/latest { "url": "https://api.github.com/repos/ansible/ansible/releases/5120666", "assets_url": "https://api.github.com/repos/ansible/ansible/releases/5120666/assets", "upload_url": "https://uploads.github.com/repos/ansible/ansible/releases/5120666/assets{?name,label}", "html_url": "https://github.com/ansible/ansible/releases/tag/v2.2.1.0-0.3.rc3", "id": 5120666, "node_id": "MDc6UmVsZWFzZTUxMjA2NjY=", "tag_name": "v2.2.1.0-0.3.rc3", "target_commitish": "devel", "name": "THESE ARE NOT OUR OFFICIAL RELEASES", ... }, "prerelease": false, "created_at": "2017-01-09T16:49:01Z", "published_at": "2017-01-10T20:09:37Z", "assets": [ ], "tarball_url": "https://api.github.com/repos/ansible/ansible/tarball/v2.2.1.0-0.3.rc3", "zipball_url": "https://api.github.com/repos/ansible/ansible/zipball/v2.2.1.0-0.3.rc3", "body": "For official tarballs go to https://releases.ansible.com\n" }
tarball_url的值在可以完成的Ansible代码中
- hosts: localhost
tasks:
- uri:
url: https://api.github.com/repos/ansible/ansible/releases/latest
return_content: true
register: json_reponse
- get_url:
url: "{{ json_reponse.json.tarball_url }}"
dest: ./ansible-latest.tar.gz
我让您调整适当的参数来回答您的问题：）

我正在使用以下食谱从GitHub版本下载并提取Linux的最新watchexec二进制文件。
- hosts: localhost
tasks:
- name: check latest watchexec
uri:
url: https://api.github.com/repos/watchexec/watchexec/releases/latest
return_content: true
register: watchexec_latest
- name: "installing watchexec {{ watchexec_latest.json.tag_name }}"
loop: "{{ watchexec_latest.json.assets }}"
when: "'x86_64-unknown-linux-musl.tar.xz' in item.name"
unarchive:
remote_src: yes
src: "{{ item.browser_download_url }}"
dest: "{{ ansible_env.HOME }}/bin/"
keep_newer: yes
extra_opts:
- --strip=1
- --no-anchored
- watchexec
tar extra_opts解释了here。
每次调用剧本时，它仍会下载二进制文件。作为改进，可以使用set_fact来缓存与解压缩文件相对应的node_id属性。

我得到了启发并扩展了剧本。 下载后，我将版本号添加到二进制文件并链接到程序。 所以我可以检查下一次运行时版本是否仍然是最新的。否则它会被重新下载和链接。
- hosts: localhost
become: false
vars:
org: watchexec
repo: watchexec
filename: x86_64-unknown-linux-gnu.tar.xz
version: latest
project_url: https://api.github.com/repos/{{ org }}/{{ repo }}/releases
tasks:
- name: check {{ repo }} version
uri:
url: "{{ project_url }}/{{ version }}"
return_content: true
register: latest_version
- name: check if {{ repo }}-{{ version }} already there

我遇到了类似的情况，但他们没有使用发行版，所以我找到了这个解决方法 - 感觉比它应该的更hacky，但它获得了最新的标签，并在发行版不存在时使用它来代替发行版.
- name: set headers more location
set_fact:
headers_more_location: /srv/headers-more-nginx-module
- name: git clone headers-more-nginx-module
git:
repo: https://github.com/openresty/headers-more-nginx-module
dest: "{{ headers_more_location }}"
depth: 1
update: no
- name: get new tags from remote
command: "git fetch --tags"
args:
chdir: "{{ headers_more_location }}"
- name: get latest tag
command: "git rev-list --tags --max-count=1"
args:
chdir: "{{ headers_more_location }}"
register: tags_rev_list
- name: get latest tag name
command: "git describe --tags {{ tags_rev_list.stdout }}"
args:
chdir: "{{ headers_more_location }}"
register: latest_tag
- name: checkout the latest version
command: "git checkout {{ latest_tag.stdout }}"
args:
chdir: "{{ headers_more_location }}"
