Continuous integration of the Python project with the WERCKER class library

Continuous integration of the Python project with WERCKER Overview: Continuous integration is a kind of development practice, which aims to change the code to the shared repository by frequent merging code, and verify the quality of the software in real time by building and automated testing.Wercker is a continuous integration and deployment platform based on containers, which can help developers automate the construction, test and deploy their applications.This article will introduce how to use the Wercker class library to achieve continuous integration of the Python project. Step 1: Install Wercker First, you need to install the WERCKER command line tools locally.You can install it by running the following commands at the terminal: $ curl -L https://s3.amazonaws.com/downloads.wercker.com/cli/stable/linux_amd64/wercker -o ~/wercker && chmod +x ~/wercker $ export PATH=$PATH:$HOME This will be downloaded and installed with Wercker Cli. Step 2: Create a warehouse on github Create a new warehouse on GitHub to store the code for the Python project. Step 3: Create Wercker configuration file Create a file called `Wercker.yml` under the root directory of the project, which is used to configure the construction process of Wercker.The following is a basic example of `Wercker.yml` configuration: yml box: python:3.8 build: steps: - script: name: Install dependencies code: | pip install -r requirements.txt - script: name: Run tests code: | pytest The above configuration specifies the use of Python 3.8 as the constructive environment and defines two construction steps.The first step is all the dependencies required for the installation project, and the second step is to run all the tests.These steps can be customized according to the actual requirements of the project. Step 4: Push the project to github Run the following command in the local project directory and push the project to the GitHub warehouse: $ git init $ git add . $ git commit -m "Initial commit" $ git remote add origin <github-repo-url> $ git push -u origin master Make sure the `GitHub-REPO-URL>` is replaced with a real github warehouse URL. Step 5: Create an application in WERCKER Now, log in to Wercker's website, create a new application, and associate it with the created GitHub warehouse. Step 6: Add environment variables If sensitive information is used in the project, such as the API key, you can add ambient variables to the WERCKER application settings to store these values in order to use it during the construction process. Step 7: Start the construction In Wercker's application page, click the "Build" button to start building a project.Wercker will automatically execute the construction steps defined in the configuration file.If everything goes well, the construction process will be successful. Step 8: View the construction log and report After the construction is completed, you can view the construction log and report to understand any problems in the construction.This information will help debug and improve projects. in conclusion: By using the WERCKER class library, the continuous integration of the Python project can be easily realized.The configuration is simple and flexible. The steps can be defined according to the requirements of the project, and the items are automatically constructed and testing after each code change.With the support of continuous integration, developers can detect and solve potential problems faster, and improve the quality and stability of software.
