# Sync App - Git
|
|
|
|
## Requirements
|
|
|
|
1. Make sure you have repository with some Kubernetes manifests
|
|
2. Make sure you have a Kubernetes cluster running with ArgoCD installed
|
|
|
|
|
|
## Objectives
|
|
|
|
1. Create a new application using the UI or CLI
|
|
1. App Name: app-demo
|
|
2. Project: project-demo
|
|
3. Kubernetes namespace: default
|
|
2. Sync the application
|
|
3. Verify the application is running by executing `kubectl get deploy` in the `default` namespace
|
|
4. Now make a change in your repository to one of the Kubernetes manifests (e.g. update deployment tag)
|
|
5. Go back to ArgoCD and check the state of the app
|
|
6. Sync the state of the application
|
|
|
|
## Solution
|
|
|
|
### UI
|
|
|
|
1. Click on "New App"
|
|
1. Insert application name: `app-demo`
|
|
2. Insert project: `project-demo`
|
|
3. Under source put the repository URL to your GitHub repo with Kubernetes manifests
|
|
1. Set path of your application
|
|
4. Under destination put the address of your Kubernetes cluster and set namespace to `default`
|
|
5. Click on "Create"
|
|
2. Click on the newly created application
|
|
1. Click on the "sync button" and click on "Synchronize"
|
|
3. Make a change in your Git repo where the Kubernetes manifests are
|
|
1. `git add .`
|
|
2. `git commit -a`
|
|
3. `git push origin <BRANCH_NAME>`
|
|
4. Go back to ArgoCD UI and check the status of the app
|
|
1. You should see it's "out-of-sync". If you don't, you may want to click on "Refresh"
|
|
2. You can also click on "App diff" to see the difference that led to "out-of-sync"
|
|
5. Click on "Sync" and "Synchronize" to sync the application
|
|
|
|
### CLI
|
|
|
|
```
|
|
argocd app create app-demo \
|
|
--project project-demo \
|
|
--repo https://fake.repo.address \
|
|
--path ./some_app_path \
|
|
--dest-namespace default \
|
|
--dest-server my.kubernetes.cluster
|
|
|
|
# In the Git repo
|
|
cd <git repo>
|
|
vi <k8s manifest>
|
|
git add .
|
|
git commit -a
|
|
git push origin <BRANCH_NAME>
|
|
|
|
# Check app state
|
|
argocd app get app-demo
|
|
|
|
# Sync app state
|
|
argocd app sync app-demo
|
|
argocd app wait app-demo
|
|
``` |
