Drone provides the ability to define environment variables scoped to individual build steps. Example pipeline step with custom environment variables:

pipeline:
  build:
    image: golang
+   environment:
+     - CGO=0
+     - GOOS=linux
+     - GOARCH=amd64
    commands:
      - go build
      - go test

Please note that the environment section is not able to expand environment variables. If you need to expand variables they should be exported in the commands section.

pipeline:
  build:
    image: golang
-   environment:
-     - PATH=$PATH:/go
    commands:
+     - export PATH=$PATH:/go
      - go build
      - go test

Please be warned that ${variable} expressions are subject to pre-processing. If you do not want the pre-processor to evaluate your expression it must be escaped:

pipeline:
  build:
    image: golang
    commands:
-     - export PATH=${PATH}:/go
+     - export PATH=$${PATH}:/go
      - go build
      - go test
