Unable to push Go app inside cloud foundry-CodePudding

I'm trying to push Go app into cloud foundry. When I try to build the binary and push it the app crashes and it returns start unsuccessful.

This is my manifest file

---
applications:
- name: project-suspension
  instances: 1
  memory: 256MB
  disk_quota: 512MB
  buildpacks: 
  - go_buildpack
  - binary_buildpack
 env:
    GOPACKAGENAME: dev.azure.com/.../service-infrastructure

I tried putting every file inside the root folder of the project but the app is still crashing when I push it. The other thing i tried is using the command flag -c "project-suspension" and it still crashes.

CodePudding user response：

As mentioned in the comment, you don't need both buildpacks. Use either the go-buildpack, if you are pushing source code, or the binary buildpack if you are building locally and pushing the binary. If pushing a binary built locally, you need to cross-compile for Linux (unless you are running Linux as your workstation).

Ex:

---
applications:
- name: project-suspension
  instances: 1
  memory: 256MB
  disk_quota: 512MB
  buildpacks: 
  - go_buildpack
 env:
    GOPACKAGENAME: dev.azure.com/.../service-infrastructure

---
applications:
- name: project-suspension
  instances: 1
  memory: 256MB
  disk_quota: 512MB
  buildpacks: 
  - binary_buildpack
  command: ./project-suspension

The latter assumes that the binary you want to run is called project-suspension and that it exists in the same directory from which cf push is run (or the same directory where you've set path: or -p.

Also, be aware that applications can fail to start for other reasons, like if the health check does not pass. The default health check is going to be port-based, so it'll expect your application to be listening on the port number set with $PORT. Make sure your app reads $PORT and listens on that port.
