I m running a jar application that uses some resources folder that needs to be in the same path as the jar:
here is an example of my folder how it uses to be :
$ ls
__files mappings wiremock-standalone-2.24.0.jar
I'm able to push the jar file using
cf push wiremock-standalone-2.24.0.jar
But not able to push the two folders mappings and __files to pcf.
When I do :
cf push wiremock/__files
Ittries to create an app named wiremock/__files:
Getting app info...
Creating app with these attributes...
+ name: wiremock/__files
path: /tmp/build/2985dd2f
What is the command line I should use ?
What you could do is add all missing files to your JAR package:
cp wiremock-standalone-2.24.0.jar wiremock-standalone-2.24.0-fat.jar
jar uf wiremock-standalone-2.24.0-fat.jar ./lib
Than your command will be exactly the same all you have to do is point to the new resources inside the Java app.
cf push is used to deploy an application to a container. Anything that is deployed with cf push is expected to be an executable app. Even if you were able to cf push wiremock/__files successfully, the files would end up in a different container and inaccessible from the container created for cf push wiremock-standalone-2.24.0.jar.
It sounds like you need the jar file, __files, and mappings to all be in the same container. To make this happen, you'll need to bundle them all into an archive and cf push them together.
As suggested by #Alex Rashkov, I added the files to the jar and that worked perfectly.
My problem was exactly the same as in the original question, I want to deploy wiremock to PCF with pre-configured mappings, so I did the following:
Started the wiremock server locally and defined the required mappings via the REST api (/__admin/mappings/import or /__admin/mappings/new)
Saved the mappings (__admin/mappings/save)
Now all the mappings will appear as files in the mappings directory
Add the mappings directory to the jar file (jar -uf wiremock-standalone-2.24.0.jar mappings). I just updated the downloaded jar file directly, but I can see where you might want to update a copy as suggested above.
push the updated jar file to PCF (java_buildpack). The wiremock server running in PCF will see the mappings in the mappings folder and have those predefined.
Thanks #Alex Rashkov for the tip!

I'm facing a similar issue to this question while trying to implement the new hooks logic on a AWS Linux 2 managed platform running Docker.
I have created my file inside this .platform/hooks/postdeploy/configure_nginx.sh
which is living in the src/ folder of my app.
I can see the file in my host after the deploy but it's never executed /var/app/current/src/.platform/hooks/postdeploy/configure_nginx.sh
It has the right privileges and I can run it if I ssh into my instance.
The EBS environment is initialized through a docker-compose file where I start 2 public containers and my custom app (in which I have put the hook folders)
The script is not being executed so I'm a bit lost on where I need to put it. FYI, my eb deploy is simply copying a Dockerrun file which is grabbing an image from one of my ECR so basically nothing is done in there.
Thanks for your help!
[SOLUTION]
I've found how it should work.
You have to create the .platform folder at the same level as the .ebextensions one.
In my case I'm deploying a zip archive simply containing my Dockerrun.aws.json and both .ebextensions and .platform folders.
So remember to zip it with the whole package before deploying it to your EBS environment.
I'm using "Google App Engine" from GCP to host a static website. I already created the website files (HTML, JS) and yaml using Visual Studio Code. I have the folder with those files stored locally in my local computer.
I downloaded the Cloud SDK Shell for Windows. I logged in to my account, and selected the project. According to videos and tutorials, I need to deploy the app using "gcloud app deploy".
However I got an error saying that an "app.yaml" file is required to deploy this directory...
I'm trying to follow this tutorial:
https://cloud.google.com/appengine/docs/standard/python/getting-started/hosting-a-static-website#before_you_begin
I'm also trying to follow the steps contained in this video:
https://www.youtube.com/watch?v=mlcO7nfQzSg
How do I specify the root folder where I have my "app.yaml" file?
Thanks in advance!!
I already tried with many commands and unfortunately none of them have worked
The particular case in which gcloud app deploy works without additional arguments is for single-service applications only and only if the command is executed in the directory in which the service's app.yaml configuration file exists (and has that exact name, can't use a different name).
For other cases deployables can/must be specified. From gcloud app deploy:
SYNOPSIS
gcloud app deploy [DEPLOYABLES …] [--bucket=BUCKET] [--image-url=IMAGE_URL] [--no-promote] [--no-stop-previous-version]
[--version=VERSION, -v VERSION] [GCLOUD_WIDE_FLAG …]
DESCRIPTION
This command is used to deploy both code and configuration to the App
Engine server. As an input it takes one or more DEPLOYABLES that
should be uploaded. A DEPLOYABLE can be a service's .yaml file or a
configuration's .yaml file (for more information about configuration
files specific to your App Engine environment, refer to
https://cloud.google.com/appengine/docs/standard/python/configuration-files
or
https://cloud.google.com/appengine/docs/flexible/python/configuration-files).
Note, for Java Standard apps, you must add the path to the
appengine-web.xml file inside the WEB-INF directory. gcloud app
deploy skips files specified in the .gcloudignore file (see gcloud
topic gcloudignore for more information).
So apart from running the command with no arguments in the directory in which your app.yaml exists is to specify the app.yaml (with a full or relative path if needed) as a deployable:
gcloud app deploy path/to/your/app.yaml
IMHO doing this is a good habit - specifying deployables is more reliable and is the only way to deploy apps with multiple services or using routing via a dispatch.yaml file.
gcloud app deploy will look at the current directory first for app.yaml. Generally you will change to the directory with app.yaml and your other files before deploying
I am new to AWS and we are trying to deploy multiple war files on a single instance of AWS Elastic Beanstalk with Tomcat 8. We have multiple services actually and we want to ensure that they are available mostly. So that ways even if there is a change in one, code changes and deployment do not affect the others. We've tried zipping the multiple wars and it works but then it again means other services won't be available in case of a change in any one of the services. Is there a way to implement this without zipping the multiple wars together and then deploying it?
If Every War file refers a different web Application then you can deploy these war files using a source bundle .
Make a Source Bundle and add each war file with in it .
Exp : MyApplication.zip
->app1.war
->app2.war
->app3.war
->ROOT.war
When Elastic Beanstalk sees that you’ve deployed a file like this it treats it differently than a normal bundle. It takes the WAR file called ROOT.war and deploys that as the root application. The rest of the WAR files are deployed in directories derived from their file names. For example, application1.war would be accessed through the /application1 path.
Now change the extraction script provided by HostManager . find the script in given file :
/opt/elasticbeanstalk/srv/hostmanager/lib/elasticbeanstalk/hostmanager/utils/tomcatutil.rb
OR You can find the script by given command :
grep -i -r ROOT.war /opt/elasticbeanstalk/srv/hostmanager/lib/:
I am trying to upload files to my bluemix app and I am having problems using and understanding the file system. After I have succesfully uploaded files I want to give their path on my configuration files.
Specifically, I want to upload a jar file to the server and later use it as javaagent.
I have tried approaching this isuue from several directions.
I see that I can create a folder in the liberty_buildpack and place the files inside I can later access it on the compilation-release phases from the tmp folder:
/tmp/buildpacks/ibm-websphere-liberty-buildpack/lib/liberty_buildpack/my_folder
Also I can see that in the file system that I see when building and deploying the app I can copy only to the folder located in:
/app
So I copied the JAR file to the app file and set it as a javaagent using 2 method:
Manually set enviorment variable JAVA_OPTS with java agent to point to /app/myjar.jar using cf set-env
Deploy a war file of the app using cf push from wlp server and set the java agent inside the server.xml file and attribute genericJvmArguments
Both of those methods didnt work, and either the deploy phase of the application failed or my features simply didnt work.
So I tried searching the application file system using cf files and came up with the app folder, but strangly it didn't have the same file as the folder I deploy and I couldn't find any connection to the deployed folder ot the build pack.
Can someone explain how this should be done correctly? namely, uploading the file and then how should I point to it from the enviorment variable/server file?
I mean should it be /app/something or maybe other path?
I have also seen the use of relative paths like #droplet.sandbox maybe its the way to address those files? and how should I access those folders from cf files
Thanks.
EDIT:
As I have been instructed in the comments I have added the jar file to the system, the problem is that when I add the javaagent variable to the enviorment variable JAVA_OPTS the deploy stage fails with the timeout error:
payload: {... "reason"=>"CRASHED", "exit_status"=>32, "exit_description"=>"failed to accept connections within health check timeout", "crash_timestamp"=>
1433864527}
The way I am assigning the javaagent is as follows:
cf set-env myApp JAVA_OPTS "path/agent.jar"
I have tried adding several location:
1. I have found that if I add the jar files to my WebContent folder I can find it in: /app/wlp/usr/servers/defaultServer/apps/myapp.war/resources/
2. I have copied the jar file from the /tmp location in the compilation phase to /home/vcap/app/agent.jar
3. I have located the jar file in /app/.java/jre/lib
none of those 3 paths worked.
I found out that if I give a wrong path the system behaves the same so it may be a path problem.
Any ideas?
Try this:
Put your agent jars in a folder called ".profile.d" inside your WAR package;
cf se your-app JAVA_OPTS -javaagent:/home/vcap/app/.profile.d/your.jar ;
Push the war to Bluemix.
Not sure if this is exactly the right answer, but I am using additional jar files in my Liberty application, so maybe this will help.
I push up a myapp.war file to bluemix. Within the war file, inside the WEB-INF folder, I have a lib folder that contains a number of jar files. The classes in those jar files are then used within the java code of my application.
myapp.war/WEB-INF/lib/myPlugin.jar
You could try doing something like that with the jar file(s) you need, building them into the war file.
Other than that, you could try the section Overlaying the JRE from the bluemix liberty documentation to add jars to the JRE.
I'm trying to upload an index.html page to Bluemix using the cf CLI. I'm not sure if I'm approaching this with the right mentality. I'm thinking of uploading this HTML file as we usually do with normal hosting services, through FTP. With Bluemix I assume I should be using the push command in cf and treat this index.html as an app. Is this right?
If this is right, I'm not getting how to use this command. Can you give me an example of full command to push/upload this page?
The cf push command would be the one to use to 'upload' your application to the Bluemix server. However, it does more than just upload. In Bluemix there is a concept of a runtime or buildpack, the idea being this will be the runtime to run your application. So if you uploaded a Java application you would pair it with the Java Liberty Buildpack/runtime. If you uploaded a PHP application then you would pair it with the PHP buildpack.
If you pushed just a HTML file with no buildpack then you would likely get an error indicating the buildpack could not be determined. Bluemix tries to guess the type of buildpack you want based on the type of files uploaded, and then pull the buildpack from an internal cache. The cf push command allows you to explicitly state the buildpack to use -b so there is no guess work and no need to rely on only the buildpack that Bluemix currently knows about.
In your case, for a static HTML file you would need some type of http server like nginx as the 'runtime'. Notice that Bluemix currently does not have a built-in buildpack for this, so you'd have to get it from somewhere else. There are a few buildpacks available already, but the best one to use would be this one: https://github.com/cloudfoundry-community/staticfile-buildpack . To use it simply supply that url with the -b option on the cf push command from the root directory of your application i.e.
cf push yourappname -b https://github.com/cloudfoundry-community/staticfile-buildpack
Be sure you are issuing this command from your app directory.
The yourappname will be part of the URL for your website/app
For an actual example, we will upload your index.html which exist in folder C:\Users\XYZ\Documents\projects\ProjectHelloWorld and we will call this app HelloWorld. Here is what we would do:
C:\> cd C:\Users\XYZ\Documents\projects\ProjectHelloWorld
C:\Users\XYZ\Documents\projects\ProjectHelloWorld> cf push HelloWorld -b https://git
hub.com/cloudfoundry-community/staticfile-buildpack
Bluemix will then upload everything in that local directory to the server and also grab the buildpack from the URL location and stage your application code with the buildpack, Bluemix will then attempt to start the application. This is an example Bluemix output when the push command succeed:
Creating app HelloWorld in org xyz#gmail.com / space test as xyz#gmail.com...
OK

For more details:
See the github page for the buildpack on how to structure your application (public folder etc)
See Bluemix Docs website. It has a lot of demos and examples.
See Takehiko Amano's Bluemix demo. Is a good and easy to understand demo.
you can either deploy your app directly using "cf push ..." or via creating a manifest.yml file.if you create manifest.yml file inside you app code path,only cf push is sufficient.
below is the reference link for this:

Hope it clears your doubt!!
Yeah as whitfiea mentioned its pretty simple. You need to use the cf push command. For example if you had a static website with an index.html file.
For example the following.
[02:30 PM] jsloyer#jeffs-mbp [friendme]>ls
index.html
To push that app to Bluemix run the following.
cf push yourappname -b https://github.com/cloudfoundry-community/staticfile-buildpack.git
https://www.ng.bluemix.net/docs/#starters/index.html
In this browse Creating Web Apps->Building a web app-> Uploading an app
It says;-
You can use a sample Java™ web application to get started. This sample application displays the list of environment variables that are available. You can download the sample Java web application from the community sample site. The sample application contains a single JSP and the WEB-INF/web.xml file.
Extract the downloaded file, and a new directory that contains the application is created. From the newly created application directory, issue the cf push command. In the following example, you can use a unique name testEnv for the application and 512M for memory allocation. The name must be unique in the whole Bluemix environment.
$ cf push testEnv -m 512m
->So as per your requirement, you can add your html file along with the JSP file before uploading the application.
Hopefully this help...
