ok, i solve that by curl shell script with the api environnment by search/create/update environment

the get environnment doesnt work with api v4, i cant found existing env id, seem bug, i must seach on all environment list
if the env id is existing or not

i use create or update for the external url

gitlab yml is to limited and that was not intelligent, not cool

EXTERNAL_URL=http://www.google.fr
NAME=“myreport-url”

curl --data “name=$NAME&external_url=$EXTERNAL_URL” --header “PRIVATE-TOKEN: $TOKEN” “$PATH/$PROJECT_ID/environments”

ENVIRONMENT_ID=1234
curl --request PUT --data “name=$NAME&external_url=$EXTERNAL_URL” --header “PRIVATE-TOKEN: $TOKEN” “PATH/$PROJECT_ID/environments/$ENVIRONMENT_ID”

environments:
name : myreport-url

i hope they can improve scope environment with local variable or evaluate from script url=$(./myurl.sh)
