A repository for the Docker and Kubernetes: The Complete Guide course on Udemy, taught by Stephen Grider.
This repository was started a long time ago, when I first started this course. At the time, I only finished the Docker part of the course, which was extremely helpful. Now, years later, I'm going to finish the course, as both Kubernetes and AWS I want to laearn for my future career.
The OLD directory contains all the code I made when I first started the course. Everything else is new and will follow the structure of the course, unlike the old sections.
The most important sections are section 7, 11 and 16.
- Decided to use Github Actions instead of Travis CI, as I'm already familiar with GA. I also don't want to setup a Travis CI account.
- Rewrote some Dockerfiles to use alpine images, npm ci instead of npm i.
- Had to make some changes in the 7_deploy_aws.yml workflow to account for the fact this is a monorepo.
- Had to include certificates for postgres. The course doesn't mention this, but it's necessary for the server to work, and to connect to the database. Source
- Uploaded the yml files for the Pod and Service.
- Uploaded a README.md file with some commands and explanation about WSL2 setup.
- Replaced the Pod yml file from the previous section with a Deployment file.
- Uploaded the Service yml file from previous section.
- Uploaded an expanded README.md file from the previous section, with more commands, better terminology and a note about updating image versions.
- Updated README.md with a note about accessing containers inside a node.
- Using the app files directly from the course repo, as they are already setup for local k8s.
- Using a k8s ConfigMap and Secret objects for the environment variables, instead of writing them directly in the yml files.
The template for the objects is stored in .envs.template. Locally, the file was named .envs.yml. I've changed it here to:
- Hide secrets from the repo.
- Avoid the .yml file to be picked up by kubectl commands.
- Included an image schema for a node using an Ingress Controller.
- Included a README.md file with setup instructions for WSL2 and accessing the Ingress service.
- Used the ConfigMap and Secret objects from section 14, instead of configuring them manually in the yml files/google cloud console.
- Modified the github workflow to replace the secrets in the k8s yml files with the actual values from repo secrets using sed.
- Included a README.md file with commands to authenticate to the cluster, install helm and ingress inside the cluster.
- Added gke.png and live.png file to show screenshots of the GKE dashboard and the live app.
- I couldn't follow these steps, as I don't own a domain, but I've written the k8s configs and the helm installation commands anyway.
- Included a README.md file with commands to install cert manager with helm.
- Added a certificates.yml config file with the certificate issuer and the certificate objects.
- Added an ingress.yml file that inclues changes for the ingress object to work with the certificate issuer and certificate objects.
- Included a skaffold.yml file with a mockup configuration.
- Included an image.png file with a schema of the skaffold workflow/a kind of explanation of how skaffold works.
- Added a brief explanation of skaffold in the README.md file along with docs link.
