Netlify continuous deployment#
This guide shows you how to configure Semaphore to continuously deploy a static website to Netlify.
Before getting started, you'll need:
Writing a deployment pipeline#
Create a deployment pipeline as a new file in your
# .semaphore/production-deploy-netlify.yml version: v1.0 name: Deploy website agent: machine: type: e1-standard-2 os_image: ubuntu1804 blocks: - name: 🏁 Deploy task: # Mount a secret which defines /home/semaphore/.netlify/config.json and # /home/semaphore/.netlify/state.json. # For info on creating secrets, see: # https://docs.semaphoreci.com/essentials/using-secrets/ secrets: - name: netlify-authentication jobs: - name: Copy to netlify commands: - npm install netlify-cli -g # restore the website cached as website-build - cache restore website-build # deploy the contents of the public directory - netlify deploy --dir=public --prod
The pipeline shown above assumes that the website files are generated in
public directory and
with the following key:
website-build. You may need to adjust the last two
commands of the job to suit your needs.
Adding a promotion to deployment#
Next, add a promotion
to your existing
semaphore.yml file, as shown below:
- name: Netlify Production deploy pipeline_file: production-deploy-netlify.yml auto_promote: when: "result = 'passed' and branch = 'master'"
This will start the deployment on every successful revision on the master branch. For more details regarding promotions, consult the reference documentation.
Managing Netlify credentials#
To obtain your Netlify credentials:
Install the netlify command line interface with the following command:
bash $ npm install netlify-cli -g
Log in to your Netlify account, as shown below:
bash $ netlify login
This opens a browser window, follow the instructions to get authorized.
Link your project's directory with the Netlify site. The actual command depends on whether you are updating an existing site or creating a new one:
If you are creating a new site, enter the following command:
bash $ cd /your/project/path $ netlify init
If you are updating a previously existing site, enter the following command:
bash $ cd /your/project/path $ netlify link
Storing credentials on Semaphore#
You need to upload two files to Semaphore in order to allow access to your Netlify account and site. Secrets are the best way to store private data such as authentication tokens and passwords. You can securely send the files to Semaphore using sem CLI, as shown below:
$ cd /your/project/path $ sem create secret netlify-authentication \ --file .netlify/state.json:/home/semaphore/.netlify/state.json \ --file ~/.netlify/config.json:/home/semaphore/.netlify/config.json
To see the secrets stored on Semaphore enter the following command:
$ sem get secrets
Launching your first deployment#
The workflow will start as soon as the changes are pushed to your repository, as shown below:
$ git add .semaphore/production-deploy-netlify.yml $ git add .semaphore/semaphore.yml $ git commit -m "add deployment" $ git push
That’s all. Your website will be automatically deployed on every successful update of the master branch. With a setup such as this, you can ship updates quickly while preventing any errors from reaching your site.
