It creates a folder structure, manages a symlink for the current release and cleans up old releases. - Running it with the O(state=query) or O(state=present) will return the C(deploy_helper) fact. C(project_path), whatever you set in the O(path) parameter, C(current_path), the path to the symlink that points to the active release, C(releases_path), the path to the folder to keep releases in, C(shared_path), the path to the folder to keep shared resources in, C(unfinished_filename), the file to check for to recognize unfinished builds, C(previous_release), the release the 'current' symlink is pointing to, C(previous_release_path), the full path to the 'current' symlink target, C(new_release), either the O(release) parameter or a generated timestamp, C(new_release_path), the path to the new release folder (not created by the module). attributes: check_mode: support: full diff_mode: support: none options: path: type: path required: true aliases: ['dest'] description: - The root path of the project. Returned in the C(deploy_helper.project_path) fact. state: type: str description: - The state of the project. - V(query) will only gather facts. - V(present) will create the project C(root) folder, and in it the C(releases) and C(shared) folders. - V(finalize) will remove the unfinished_filename file, create a symlink to the newly deployed release and optionally clean old releases. - V(clean) will remove failed & old releases. - V(absent) will remove the project folder (synonymous to the M(ansible.builtin.file) module with O(state=absent)). choices: [present, finalize, absent, clean, query] default: present release: type: str description: - The release version that is being deployed. Defaults to a timestamp format C(%Y%m%d%H%M%S) (for example V(20141119223359)). This parameter is optional during O(state=present), but needs to be set explicitly for O(state=finalize). You can use the generated fact C(release={{ deploy_helper.new_release }}). releases_path: type: str description: - The name of the folder that will hold the releases. This can be relative to O(path) or absolute. Returned in the C(deploy_helper.releases_path) fact. default: releases shared_path: type: path description: - The name of the folder that will hold the shared resources. This can be relative to O(path) or absolute. If this is set to an empty string, no shared folder will be created. Returned in the C(deploy_helper.shared_path) fact. default: shared current_path: type: path description: - The name of the symlink that is created when the deploy is finalized. Used in O(state=finalize) and O(state=clean). Returned in the C(deploy_helper.current_path) fact. default: current unfinished_filename: type: str description: - The name of the file that indicates a deploy has not finished. All folders in the O(releases_path) that contain this file will be deleted on O(state=finalize) with O(clean=true), or O(state=clean). This file is automatically deleted from the C(new_release_path) during O(state=finalize). default: DEPLOY_UNFINISHED clean: description: - Whether to run the clean procedure in case of O(state=finalize). type: bool default: true keep_releases: type: int description: - The number of old releases to keep when cleaning. Used in O(state=finalize) and O(state=clean). Any unfinished builds will be deleted first, so only correct releases will count. The current version will not count. default: 5 notes: - Facts are only returned for O(state=query) and O(state=present). If you use both, you should pass any overridden parameters to both calls, otherwise the second call will overwrite the facts of the first one. - When using O(state=clean), the releases are ordered by I(creation date). You should be able to switch to a new naming strategy without problems. - Because of the default behaviour of generating the C(new_release) fact, this module will not be idempotent unless you pass your own release name with O(release). Due to the nature of deploying software, this should not be much of a problem. extends_documentation_fragment: - ansible.builtin.files - community.general.attributes ai # General explanation, starting with an example folder structure for a project: # root: # releases: # - 20140415234508 # - 20140415235146 # - 20140416082818 # # shared: # - sessions # - uploads # # current: releases/20140416082818 # The 'releases' folder holds all the available releases. A release is a complete build of the application being # deployed. This can be a clone of a repository for example, or a sync of a local folder on your filesystem. # Having timestamped folders is one way of having distinct releases, but you could choose your own strategy like # git tags or commit hashes. # # During a deploy, a new folder should be created in the releases folder and any build steps required should be # performed. Once the new build is ready, the deploy procedure is 'finalized' by replacing the 'current' symlink # with a link to this build. # # The 'shared' folder holds any resource that is shared between releases. Examples of this are web-server # session files, or files uploaded by users of your application. It's quite common to have symlinks from a release # folder pointing to a shared/subfolder, and creating these links would be automated as part of the build steps. # # The 'current' symlink points to one of the releases. Probably the latest one, unless a deploy is in progress. # The web-server's root for the project will go through this symlink, so the 'downtime' when switching to a new # release is reduced to the time it takes to switch the link. # # To distinguish between successful builds and unfinished ones, a file can be placed in the folder of the release # that is currently in progress. The existence of this file will mark it as unfinished, and allow an automated # procedure to remove it during cleanup. # Typical usage - name: Initialize the deploy root and gather facts community.general.deploy_helper: path: /path/to/root - name: Clone the project to the new release folder ansible.builtin.git: repo: ansible.builtin.git://foosball.example.org/path/to/repo.git dest: '{{ deploy_helper.new_release_path }}' version: v1.1.1 - name: Add an unfinished file, to allow cleanup on successful finalize ansible.builtin.file: path: '{{ deploy_helper.new_release_path }}/{{ deploy_helper.unfinished_filename }}' state: touch - name: Perform some build steps, like running your dependency manager for example composer: command: install working_dir: '{{ deploy_helper.new_release_path }}' - name: Create some folders in the shared folder ansible.builtin.file: path: '{{ deploy_helper.shared_path }}/{{ item }}' state: directory with_items: - sessions - uploads - name: Add symlinks from the new release to the shared folder ansible.builtin.file: path: '{{ deploy_helper.new_release_path }}/{{ item.path }}' src: '{{ deploy_helper.shared_path }}/{{ item.src }}' state: link with_items: - path: app/sessions src: sessions - path: web/uploads src: uploads - name: Finalize the deploy, removing the unfinished file and switching the symlink community.general.deploy_helper: path: /path/to/root release: '{{ deploy_helper.new_release }}' state: finalize # Retrieving facts before running a deploy - name: Run 'state=query' to gather facts without changing anything community.general.deploy_helper: path: /path/to/root state: query # Remember to set the 'release' parameter when you actually call 'state=present' later - name: Initialize the deploy root community.general.deploy_helper: path: /path/to/root release: '{{ deploy_helper.new_release }}' state: present # all paths can be absolute or relative (to the 'path' parameter) - community.general.deploy_helper: path: /path/to/root releases_path: /var/www/project/releases shared_path: /var/www/shared current_path: /var/www/active # Using your own naming strategy for releases (a version tag in this case): - community.general.deploy_helper: path: /path/to/root release: v1.1.1 state: present - community.general.deploy_helper: path: /path/to/root release: '{{ deploy_helper.new_release }}' state: finalize # Using a different unfinished_filename: - community.general.deploy_helper: path: /path/to/root unfinished_filename: README.md release: '{{ deploy_helper.new_release }}' state: finalize # Postponing the cleanup of older builds: - community.general.deploy_helper: path: /path/to/root release: '{{ deploy_helper.new_release }}' state: finalize clean: false - community.general.deploy_helper: path: /path/to/root state: clean # Or running the cleanup ahead of the new deploy - community.general.deploy_helper: path: /path/to/root state: clean - community.general.deploy_helper: path: /path/to/root state: present # Keeping more old releases: - community.general.deploy_helper: path: /path/to/root release: '{{ deploy_helper.new_release }}' state: finalize keep_releases: 10 # Or, if you use 'clean=false' on finalize: - community.general.deploy_helper: path: /path/to/root state: clean keep_releases: 10 # Removing the entire project root folder - community.general.deploy_helper: path: /path/to/root state: absent # Debugging the facts returned by the module - community.general.deploy_helper: path: /path/to/root - ansible.builtin.debug: var: deploy_helper N) AnsibleModule) to_nativecTeZdZdZdZdZdZdZdZdZ dZ d Z d Z d Z d Zy ) DeployHelperc||_|j|j|_|jd|_|jd|_|jd|_|jd|_|jd|_|jd|_ |jd|_ |jd|_ |jd |_ y) Nclean current_path keep_releasespathrelease releases_path shared_pathstateunfinished_filename) moduleload_file_common_argumentsparams file_argsr r r rrrrrr)selfrs s/home/dcms/DCMS/lib/python3.12/site-packages/ansible_collections/community/general/plugins/modules/deploy_helper.py__init__zDeployHelper.__init__s ::6==I]]7+ "MM.9#]]?;MM&) }}Y/ #]]?;!==7]]7+ #)==1F#G c tjj|j|j}tjj|j|j}|j r5tjj|j|j }nd}|j |\}}|js8|jdk(s|jdk(rtjd|_|jr+tjj||j}nd}|j||||||j||jd S)Nquerypresentz %Y%m%d%H%M%S) project_pathr rrprevious_releaseprevious_release_path new_releasenew_release_pathr) osrjoinr rr_get_last_releaserrtimestrftimer)rr rrr r!r#s r gather_factszDeployHelper.gather_facts%s ww||DIIt/@/@A  TYY0B0BC   '',,tyy$2B2BCKK262H2H2V//||w!6$** :Q==8DL <<!ww||M4<<H # !II(*& 0%:<< 0#'#;#;  rctjj|sytjj|s|jj d|z|jj s tj|dyy#t$rE}|jj dt|ztjYd}~yd}~wwxYw)NF %s exists but is not a directorymsg) ignore_errorszrmtree failed: %s)r- exceptionT) r$rlexistsisdirr fail_json check_modeshutilrmtree Exceptionr traceback format_exc)rres r delete_pathzDeployHelper.delete_pathCswwt$ww}}T" KK ! !&H4&O !
