Deploy a Python Visualization Panel App to Google Cloud Run

Key Takeaways

hello everyone today i would like to talk about how to deploy a python app or dashboard to google cloud run with three simple scripts and also how to automate your google cloud setup through cloud build and terraform first let's set up our google cloud account the google cloud run documentation mentioned the following steps you need to do to enable running a project so first let's go to the project select selector you will need to create a new project here i created one called panel cloud run so i'm just gonna use this project for now i like to keep my project id the same as my project name so that i can keep track of my project um and then second you want to go to this link to confirm that billing is enabled and also then install the cloud sdk following this link so i have done all that so once we have uh downloaded the google cloud sdk you should be able to do gcloud in it to initialize the google cloud sdk on your local machine you can also do cloud config set project panel cloud run to set your current project to the project id you want it to be okay so that's it for the setup in terms of creating the app there are three scripts we need to create a panel app and then deploy it the first one app.pi this is the python file that creates the panel app to run this app locally you can simply do conda install panel edge replot and run panel serve app.pi second we have the requirements.txt which lists all the package dependencies of our panel app so for our panel app we only need panel bokeh and h3plot the third file we need is the docker file installs python and its project's dependencies and then run the commands panel serve app.pi to run our panel app okay with everything ready i have um so i have this repo in my local machine so i can just direct um myself into this folder this is the same thing and then to deploy my app i can simply run cloud run deploy we need to define the service folder and then let it run so after a few minutes you should see the service url showing up and then let's go to this url and take a look cool it seems working and then if we go to our dashboard and then go to the cloud rom uh so this is the information of the app we just deployed we can delete this one if we don't want this anymore and then this page should give us a 404. okay so the next thing i would like to talk about is to deploy app to google cloud run using terraform so when we did the gcloud run deploy we have to define the region of the project we also need to enable a bunch of services apis if we're running it the first time terraform can help us capture all those decisions in code so that can we have a place to see how the infrastructure is exactly doing and how it is set up to use terraform with google cloud round there are two parts part one is to use cloudbuild.yaml file to build a container image to execute your app with this cloudbuild.yml file we could simply do cloud builds submit to submit a build using google cloud build okay so here's the docker images we have under our project so right now we see there's no pro no docker image here but after a few minutes after this command finished running we should see a darker image now this finished running let's see if anything showed up so yeah so here we see a docker image uploaded to our container registry under the current project so that is part one part two part two is to use terraform so we have a file called main.pdf this is a terraform configuration file it does the following things first it creates a variable project for us so we we can define what project we want in the command line it enables the crowd the cloud round service it specifies the crowd run services for example we use the image that we just uploaded from from the cloud build in the cloud run service here we also set the service public and then we return our service url so this defines everything we need to be able to create and run a cloud run service okay so in order to run terraform first of all we need to if you're running it locally like i do you need to do con install conda forge terraform i already did that so let's see conda list terraform you can see i have terraform installed in my environment already and then we can do terraform in it to initialize terraform next we can do a terraform plan variable project equals your project name here i have piano crowd cloud run this gives us a chance to review your execution plan so you can see this is the things we're gonna do with our google cloud project and after we confirm everything looks good we can do terraform apply to the project we want so now we got another service url let's take a look cool now we have this app served again using terraform if you would like to remove the cloud run service you can also do terraform destroy or you can simply go to the project list and delete your project that's probably the safest way to to delete an app so that's it for today's video thank you so much for watching bye bye
