I have a Golang app running on Google Cloud App Engine that I can update manually with "gcloud app deploy" but I cannot figure out how to schedule automatic redeployments. I'm assuming I have to use cron.yaml, but then I'm confused about what url to use. Basically it's just a web app with one main index.html page with changing content, and I would like to schedule automatic redeployments... how do I have to go about that?
If you want to automatically re-deploy your app when the code changes, you need what's called CI/CD (Continuous integration/deployment). What a CI does is, for each new commit to your repository, check out the new code and run a test script. If all the tests pass (or if you don't have any tests at all), the CI server can then deploy your code to App Engine, all automatically.
One free (for open-source projects) CI provider is Travis CI. To configure it, you need to make an account with Travis, and a file called .travis.yml in the root of your repository. To set up App Engine deploys, you can follow this guide to set up a service account and add the encrypted file to your repo. It will run a gcloud app deploy from a container on their servers, whenever you push code to a certain branch (master by default) in your repo.
Another option, which avoids setting up CI at all, is to simply change your app to generate the dynamic parts of the page when it gets requested. Reading the documentation for html/template would point you in the right direction.

I followed the documentation here https://devcenter.heroku.com/articles/pipelines and setup a pipeline with two stages:
The above link only talks about how to promote an app, without specifying how to deploy, this section specifically (we can read beyond this point and see there is no instruction on how to deploy):
Pipelines let you define how your deployed code flows from one
environment to the next. For example, you can deploy code to your
staging app (which builds it into a slug) and later promote that same
slug to production. This promotion flow ensures that production
contains the exact same code that you tested in staging, and it’s also
much faster than rebuilding the slug.
So I used the same command we use for deploying non-pipeline based apps (as instructed here):
docker push registry.heroku.com/ultimate-hello-world-cra-stage/web
This appears to be a wrong approach. You can see in snapshot above that STAGING app did get deployed, but when I try to promote the app using this command heroku pipelines:promote --app ultimate-hello-world-cra-stage, I get this error: Error: Pipeline promotions are not supported on apps pushed via Heroku.
What is the correct way to deploy to a pipeline and where can I find it in the docs?
We use a Heroku pipeline for deployment review apps for our Angular app. Recently we invested in EndTest codeless automation and we need to run the test suites on every review app that is created. The url's of these review apps are dynamic in Heroku, is there a way to capture this generated url and then execute a script that would trigger my test case suite in EndTest(EndTest has an API which can consume the url).
How do I get this done in Heroku environment. I just have PROC file configured.
You could use the postdeploy script:
The app.json file has a scripts section that lets you specify a postdeploy command. Use this to run any one-time setup tasks that make the app, and any databases, ready and useful for testing. Postdeploy is handy for one-off tasks, such as:
Setting up OAuth clients and DNS
Loading seed/test data into the review app’s test database
But if you will run this script with each change to a pull request, use release phase.
The app name should be in the env variable HEROKU_APP_NAME.
I have 2 repositories residing in Bitbucket - Backend (Laravel app as the API and entry point) and Frontend (Main application front-end - VueJs app). My goal is to set up continuous deployment so whenever something is pushed in either of the repos in master (or other branch selected by me) branch it triggers something so that the whole app builds and reaches the AWS EC2 server.
I have considered/tried the following:
AWS CodePipeline and/or CodeDeploy. This looked like a great option
since the servers are in AWS as well. However, there is no support
for Bitbucket out of the box, so it would have to go to Bitbucket
Pipeline -> AWS Lambda -> AWS S3 -> AWS CodePipeline/CodeDeploy ->
AWS EC2. This seems like a very lengthy journey and I am not sure if
that's a good practice whatsoever.
Using Laravel Forge to deploy the Laravel app, and add additional steps to build the VueJS app. This seemed like a very basic solution,
however, the build process seems to fail there as it just takes long
time and crashes with no errors (whereas I can run exact same process
on my local machine or a different server hosted elsewhere). I am not
sure if this is issue with the way server is provisioned, the way
Forge runs deployment script or the server is too weak to handle it.
The main question of mine would be what are the best pracises for deploying the app of such components? I have read many tutorials/articles about deploying a NodeJS app, or a Laravel app, but haven't gotten good information about a scenario like this.
Would it be better to build the front-end app locally and version control the built JS file? Or should I create a Pipeline in Bitbucket that would build the app and then deploy it? Or is it the best to just version control and deploy the source files and leave the whole build process as the last step in the deployment process that will be done by the server that is hosting the app itself? There are also some articles suggesting hosting the whole front-end app in S3 bucket - would that be bad practise as well?
Appreciate any help and resources that would help!
From the sounds of things it sounds like you have two types of deployments you might want to run.
Laravel API: If you're using Laravel Forge already then this is a great way to go about deploying your Laravel App, takes care of most of the process and easy server management.
Vue.js App: Few things you can do here, I personally prefer using a provider like Vercel or Netlify who let you deploy your static sites/frontends for free-low costs. You can write custom build steps but they have great presets that should work out the box.
If you really want to keep everything on AWS then look into how to host static sites on AWS
My team and I were setting everything up so that Forge was in charge of deployment exclusively, while a CI cloud service would run unit/integration tests on each push to develop or master (staging or production, respectively).
Given the fact that Forge will trigger a deployment on each push to master (or any other branch), where does the CI server takes place in this model? Can I get a quick explanation of the workflow (and if possible an example CI cloud that would work with it)
Next to the auto deploy trigger Forge provides you a deploy-hook-url that can be called to trigger the deployment script. Usually the ci cloud service provides a way to customize the test/deployment process with some sort of bash scripts (curl) or gives an option to call an url after a successful run.
For example I used to use codeship for ci and they have an option in the settings called deployment where i could insert a custom script which calls the trigger url like curl -X GET https://forge.laravel.com/servers/xxx/sites/xxx/deploy/http?token=xxx
deactivate the aug-deploy trigger
customize the ci settings and call the forge-hook after successful run
I have been trying to deploy from a GitHub repository to Heroku. For pushing my changes to GitHub I am using Mac UI Client for GitHub.
Now in the heroku app setup, I changed at https://dashboard.heroku.com/apps/myapp/settings . Here I made changes in option GitHub Rep (Link your app to a GitHub repository to see commit diffs in the activity log.). I added as my github-user/repository-name
Now when i use myappname.heroky.com I am redirected to a default page which says :
Heroku | Welcome to your new app! Refer to the documentation if you
need help deploying.
In the documentation it is all commands which is going over me since i use Github UI tool.
Any idea if this can be deployed w/o using the commands?
I am asking this particular thing, since last time I used AppHarbor and it simply pulled my github rep w/o any hiccups.
Adding your GitHub repo to the Heroku app settings will not set up automatic deployments. It just allows Heroku to provide commit information in the app logs.
To achieve what you are looking for, you need to set up continuous deployment (or "CD"). The easiest way to do this is with a continuous integration (or "CI") solution.
One common CI server is Jenkins, though that will require you to set it up manually. Nowadays, there are several automated CI/CD services you can take advantage of, including Travis, CircleCI, Codeship, Snap. All of them have options to automatically deploy to Heroku after building your app (which can be trigger by a push to GitHub).
