How about using endly to automate your cloud function build, in this case you would
use go mod with vendor, where you private repo would be added to vendor folder,
Make sure that you add .gcloudignore to not incliude go.mod, go.sum
@.gcloudignore
go.mod
go.sum
The automation workflow with endly that uses private repo with credentials may look like the following
@deploy.yaml
init:
appPath: $WorkingDirectory(.)
target:
URL: ssh://127.0.0.1/
credentials: localhost
myGitSecret: ${secrets.private-git}
pipeline:
secretInfo:
action: print
comments: print git credentials (debuging only_
message: $AsJSON($myGitSecret)
package:
action: exec:run
comments: vendor build for deployment speedup
target: $target
checkError: true
terminators:
- Password
- Username
secrets:
#secret var alias: secret file i.e ~/.secret/private-git.json
gitSecrets: private-git
commands:
- export GIT_TERMINAL_PROMPT=1
- export GO111MODULE=on
- unset GOPATH
- cd ${appPath}/
- go mod vendor
- '${cmd[3].stdout}:/Username/? $gitSecrets.Username'
- '${output}:/Password/? $gitSecrets.Password'
deploy:
action: gcp/cloudfunctions:deploy
'@name': MyFn
timeout: 540s
availableMemoryMb: 2048
entryPoint: MyFn
runtime: go111
eventTrigger:
eventType: google.storage.object.finalize
resource: projects/_/buckets/${matcherConfig.Bucket}
source:
URL: ${appPath}/
