Deploying

In order to deploy, you need to perform some steps:

• Create a new workflow file for deploying your app, for example, deploy.yml
• Place the created playbook in your repository for example, ci\ansible\deploy.yaml
• Set up variables for workflow (see Inputs Variables)
• Create a workflow, configure workflow start triggers (see examles)

During deployment, ansistrano looks at the current timestamp in runner by executing date -u +%Y%m%d%H%M%SZ. Each new release is placed in a folder with a name consisting of the previously received timestamp.

If everything has been set up properly, after completing the workflow approximately the following structure will be created on the server. Check how the on your server folder structure would look like after one, two and three deployments.

-- /var/www/my-app.com
|-- current -> /var/www/my-app.com/releases/20100509145325
|-- releases
|   |-- 20100509145325
|-- shared

|-- releases
|   |-- 20100509150741
|   |-- 20100509145325

|   |-- 20100509145325
|-- shared

current - The symlink folder that point out to latest release's timestamp that exist in release folder releases - The folder where the releases are saved. This folder will have a few folders depend on how many release we want to keep before the clean up process occured shared - This folder contains shareable files that we can re-used between release. This files should not get into the repository, but are necessary for the work of the Wordpress

Rolling back

In order to rollback, you need to set up the deployment and run the rollback workflow. Workflow, will switch the current folder to the previous release.

• Create a new workflow file for rollback, for example, rollback.yml
• Place the created playbook in your repository for example, ci\ansible\rollback.yaml

Synchronization of client changes

In the process of working with the website, the client can install, change settings and add modules using the Wordpress web interface. In order for these changes to appear in the repository, it is necessary to commit from the current folder, i.e. perform the following actions (for the example described above):

cd ~/deploy/current

git add . && \
git commit -m 'Commit message' && \
git push
