Hello.
I’m using the downstream plugin, but I’m facing an issue with params.
If the trigger restarts a build that has that param already set, the new one is ignored.
This is the code of the trigger in .drone.yml:
- name: trigger
image: plugins/downstream
settings:
server: https://mydrone.com
token:
from_secret: drone_token
params:
- DOWNSTREAM_IMAGE_VER=${DRONE_COMMIT_SHA:0:8}
fork: false
repositories:
- org/myrepo@1.0
I think the issue is related to drone build restart:
$ drone build restart org/myrepo -p DOWNSTREAM_IMAGE_VER=test1 1
Number: 2
Status: pending
Event: push
[...]
In this case it works, DOWNSTREAM_IMAGE_VER=test1
$ drone build restart org/myrepo -p DOWNSTREAM_IMAGE_VER=test2 2
Number: 3
Status: pending
Event: push
[...]
In this case is not working the variable test2 is ignored, DOWNSTREAM_IMAGE_VER=test1
$ drone build restart org/myrepo -p DOWNSTREAM_IMAGE_VER=test3 1
Number: 4
Status: pending
Event: push
[...]
If i choose again the first build, it works: DOWNSTREAM_IMAGE_VER=test3
If I add more variables:
$ drone build restart org/myrepo -p DOWNSTREAM_IMAGE_VER=test4 ANOTHER_VARIABLE=myAwesomeValue 2
Number: 5
Status: pending
Event: push
[...]
In this case DOWNSTREAM_IMAGE_VER=test1 ANOTHER_VARIABLE=myAwesomeValue
mysql -e "use drone; select build_number,build_params from builds ORDER BY build_number desc LIMIT 3" -s
build_number build_params
1 null
2 {"DOWNSTREAM_IMAGE_VER":"test1"}
3 {"DOWNSTREAM_IMAGE_VER":"test1"}
4 {"DOWNSTREAM_IMAGE_VER":"test3"}
5 {"DOWNSTREAM_IMAGE_VER":"test1","ANOTHER_VARIABLE":"myAwesomeValue"}
I’ve found this conversation Drone build restart does not pass parameters - Support - Drone and maybe because of that fix if a parameter is already in the build_params, the customer parameters injected by the cli is not used.
