my project's folder structure looks like this
/folder1
/feature1
feature1.go //package feature1
go.mod
/feature2
feature2.go //package feature2
go.mod
/web
app.yaml
cloudbuild.yaml
main.go //package main (starts app)
go.mod
this is inside my /web/go.mod
module mypackage
require(
//3rd party packages
feature1 v0.0.0
feature2 v0.0.0
)
replace(
feature1 => ../folder1/feature1
feature2 => ../folder1/feature2
)
if i run GO111MODULE=on go build this compiles fine and i can run my project.
however, if i do a gcloud app deploy
i get the following errors:
go: parsing ../folder1/feature1/go.mod: open /tmp/staging614917184/folder1/feature1/go.mod: no such file or directory
go: parsing ../folder1/feature2/go.mod: open /tmp/staging614917184/folder1/feature2/go.mod: no such file or directory
these files definitely do exist in my project (otherwise the local go build would not have worked).
here is the relevant snippet of my app.yaml
runtime: go111
env: standard
before i switched to using go.mod, the app deployed fine via the gcloud cli.
however, i need to be able to specify a specific version for some of the packages i'm using, so i want to switch to using go modules.
with the above change, the gcloud builder works ok for the initial build step, but then fails on the app deploy step (gcloud app deploy)
does app engine not support relative paths in a go.mod? if so, is it possible to make this folder structure work?
EDIT:
this ended up being the key How to authenticate a private Go Module using go 1.11 and Google App Engine Standard
since in app engine deploys the root folder structure was not uploaded, a fix is to copy over the parent folders inside your subfolder where you house your app.yaml. then you point to that new subfolder in your go.mod using the replace syntax.

I am stuck on the first page of instructions for Google App Engine
https://console.cloud.google.com/appengine/start/reception
I downloaded and installed the cloud SDK.
"gcloud init" worked.
I am stuck at "Deploy to App Engine".
When I type "gcloud app deploy" in Terminal, I get two errors.
"ERROR: An app.yaml (or appengine-web.xml) file is required to deploy this directory as an App Engine application. Create an app.yaml file using the directions at https://cloud.google.com/appengine/docs/flexible/python/configuring-your-app-with-app-yaml"
The page it says to go to does not give directions for creating the file. What is the command? Also, why is this error happening at all? If I follow the instructions on the Get Started page, I should not get an error. Some instructions must be missing or something not working when I install the SDK.
The second error I get is "ERROR: (gcloud.app.deploy) [/Users/chucky] could not be identified as a valid source directory or file."
Again, there must be instructions missing because I am following them.
Screen Shot
gcloud app deploy is for deploying a project. This means you need to have a folder with a sample project. The project will need to have an app.yaml file. Essentially, the steps are
Download and install the Google Cloud SDK
Run gcloud init to initialize the SDK (this makes you to login to Google and grant access to gcloud to your account; also sets up your default project)
Create your project (or copy an existing one) where project is your App i.e. the application you are working on. This project should have an app.yaml file.
Then deploy your project to production by running gcloud app deploy. You first have to change directory to your project folder. If you don't want to do this, you have to specify the full path to your app.yaml file.
An alternative for steps 3 - 4 is to use a Graphical User Interface (GUI) like one from us - https://nocommandline.com . You just click a button to create a new project and it will create a shell project ('hello world') with all the necessary files. To deploy your project, you also click another button 'Deploy' and it will take care of deploying your project.
From the link:
https://console.cloud.google.com/appengine/start/reception
First, you need to download the resources. You can use the Cloud SDK, Cloud Shell, directly download from github or other terminal to download the resources files. For example, you want to deploy a Python app using Cloud SDK in Windows OS:
Install and open Cloud SDK.
Copy the resources file from github:
From Cloud SDK run:
git clone https://github.com/GoogleCloudPlatform/python-docs-samples
Go to directory of your application files:
cd python-docs-samples/appengine/standard_python3/hello_world
Deploy and browse your application
Deploy using the command:
gcloud app deploy --project PROJECTID
Browse using the command:
gcloud app browse --project PROJECTID
If you see the Hello World! you've successfully deployed your application.
This is the first time I am deploying something on cloud, and I followed article.
I have created application, and want to deploy it on Google Cloud. While doing it I am getting error for app.yaml file.
My app.yaml is,
When I execute "ls" command, it display only 1 file,
The problem is that the command gcloud app deploy is unable to find your application app.yaml file.
If you do not provide any argument to gcloud app deploy it will look for an app.yaml file in the current directory.
It seems for your screenshot that you are in the Cloud Shell home directory, one directory above the one that contains your code and the actual app.yaml file, the one named xxxx-point-gcp.
Please, either change the working directory to xxxx-point-gcp and then run gcloud app deploy, or run gcloud app deploy passing as argument the full path to the app.yaml file:
gcloud app deploy ~/xxxx-point-gcp/app.yaml
Please, substitute the xxxx placeholders for the appropriate paths.
Please, see the relevant documentation.
You need to run gcloud app deploy from the folder which contains app.yaml file.
I am trying to deploy an Helidon MP project to Google Cloud App Engine using java11 runtime but having trouble to define the app.yaml properly.
Tried to deploy the jar file directly using the below app.yaml using the command $ gcloud app deploy cord.jar. The app gets deployed but empty page on view.
runtime: java11
entrypoint: 'java -jar cord.jar'
Tried to modify the codewbase adding appengine\app.yaml to <project>\src\main\appengine\app.yaml and with contents as below and using command $ gcloud app deploy pom.xml:
runtime: java11
instance_class: F1
In all cases, the app got deployed but page loads empty.
They have examples on github but unfortunately not yet with Helidon.
I've put together an example for Helidon.
A couple things to note:
Make sure your application obeys the PORT environment variable, and configures its server to use that port.
Make sure your app.yaml is in the same directory as your jar and defines a custom entry point. For example:
runtime: java11
entrypoint: java -Xmx64m -jar helidon-quickstart-se.jar
Helidon uses "thin" jars and App Engine seems to handle this AOK as mentioned here: https://cloud.google.com/appengine/docs/standard/java11/runtime#application_startup
As an answer to my question.. issue for the page not loading was because of port 9090 that we were using (defined in src/main/resources/META-INF/microprofile-config.properties file). After i changed it to default 8080, my app worked.
microprofile-config.properties:
# Application properties. This is the default greeting
app.greeting=Hello
# Microprofile server properties
server.port=8080
server.host=0.0.0.0

Helidon MP example for Google App Engine
There is a github thread regarding this and so far the current workaround is to add an app.yaml file similar to the one for the frameworks like Spring Boot or Vert.x
I have followed the tutorial where the github sample of the other responses is and it worked for me.
First I have cloned the repository and I used the quickstart mp:
git clone https://github.com/barchetta/helidon-google-app-engine-example/
cd helidon-google-app-engine-example/helidon-quickstart-mp
Then I have built and run the application and check if the port responds.
mvn package
export PORT=8888
java -jar target/helidon-quickstart-mp.jar
After all these previous steps I was able to see in localhost the result of the application.
For deploying I created the app.yaml file named "helidon-mp-app.yaml" and wrote this configuration inside:
runtime: java11
entrypoint: java -Xmx64m -jar helidon-quickstart-mp.jar
And copied it to the target/ directory:
cp helidon-mp-app.yaml target/
As the last configuration file, the file ".gcloudingonre" which also needs to be moved to target/
# Exclude everything. Then include just the app jar and runtime
# dependencies in libs/
*
*/
*/**
!helidon-quickstart-mp.jar
!libs/
!libs/**
Then as all the configuration files are ready, I executed
gcloud app deploy target/helidon-mp-app.yaml
gcloud app browse
And appending "/greet" in the URL we can see the result:
{"message":"Hello World!"}
I'm newbie on react, I did 2 paged website for exercise, all is working well on my localhost.
But i'm confused about how upload project to my linux server.
What i did ?
I create react app via terminal with this command :
create-react-app react-demo-project
Terminal create my project and in project root i have node_modules directory.
so here is i have some questions:
1- React project will work normally on linux hosting?
2- I need to all my project upload to ftp? Because there is arround 20.000 file in node_modules directory.
With this command build your app :
npm run build
Build folder has created in your project directory, open index.html in your browser and check output...
If you saw a blank page (after build and opening index.html) , you must change the main js file path in the index.html :
default is : src="/static/js/main.ddfa624a.js"
change to : src="./static/js/main.ddfa624a.js"
I changed js path and this worked !
create-react-app has a command to bundle your app to a ready to deploy state.
npm run build
This command will bundle your app in /build folder. With the contents of this folder you can deploy your app in any hosting environment. You don't need to install your packages and libraries manually when you use this command. More information about using this command and deploying your app in different hosting environments can be found create-react-app README
Deployment
npm run build creates a build directory with a production build of
your app. Set up your favorite HTTP server so that a visitor to your
site is served index.html, and requests to static paths like
/static/js/main.<hash>.js are served with the contents of the
/static/js/main.<hash>.js file.
1- React project will work normally on linux hosting?
Yes, it will work in all webservers, unless you have server side rendering (SSR)
2- I need to all my project upload to ftp? Because there is arround
20.000 file in node_modules directory.
Files in node_modules will NOT go to your web server. These are development dependency files used only during development.
Run npm run build
This will create a folder called build in project root. This will have all html, css , images and js files
Copy all files and folders in build folder to your site root.
If your site has to be hosted in a sub folder in root you need to do the below, otherwise you will see a blank page. This is because your static files (css, js etc) are not loaded correctly.
Open package.json
Add a new entry homepage: /your_subfolder/
It will look like this
Now do steps mentioned above and your site should work fine
Add this line to package.json:
"homepage": "./"
That should make it work without the need to adjust index.html after every build.
I am wondering if it is possible to deploy react.js web app that I've built to a share hosting site that does not have node.js installed?
I use webpack to build the application and it creates normal html, js, css file. I uploaded the static folder that includes all those html, js(bundle.js) and css files, but when I request the site, the server reply with 404 bundle.js not found response.
Use npm run build, you should get a folder with the index html file inside that will run your app. Try this with xampp first before you actually deploy to your server.
Here is everything step by step
npm run build
or
yarn run build
it will generate a build folder that looks like this:
Copy everything and move it to the htdocs in xampp or ftp upload the directory to the public_html file in your hosting
Yes you sure can put react on a shared hosting provider.
Seeing as you're getting a 404 error (not found), you are probably referencing your react file/bundle incorrectly. It might not even be named bundle.js if you're using a boilerplate to create your application.
Can you give more information? What does your index.html file look like? What does your directory structure look like? If you are able to post these files I can tell you what the issue is.
Update:
The answer below should be accepted. (Although this would assume that you have the ability to make a build which you have not verified or not.)
Make a build using the build command through whatever boilerplate you used. Deploy those files on your shared hosting server. Make sure that index.html is at the root of where your server is expecting the root to be and your app should be live.
For deploying a react app on a shared hosting you need to create a production build. Production build is a pack of all your react code and its dependencies.
in most shared hosting we put our site/app inside a public_html directory so if we hit www.yourdomain.com it serves the code from public_html directory.
so if your react app is ready to go, edit your package.json file add a new key value:
"homepage":"http://yourdomain.com"
then create a build using following command:
npm run build
after running the command you will see a new directory named build in your app root. It will contain js and css for the app and a index.html file. You need to upload all the content inside build directory to public_html directory, and that's all, go to your domain and your app will be working just fine.
