Cloning

Drone automatically clones your repository before executing your pipeline steps. No special configuration is required. In some cases, however, you may need to customize, override or disable the default clone behavior.

The --depth flag

The default clone configuration does use the --depth flag. You can enforce a clone depth by declaring a clone block and adding the depth attribute:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13

kind: pipeline
type: kubernetes
name: default

clone:
  depth: 50

steps:
- name: build
  image: golang
  commands:
  - go build
  - go test

The --tags flag

The default clone configuration does not use the --tags flag. If you would like to fetch tags you should handle this as a step in your pipeline. For example:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15

kind: pipeline
type: kubernetes
name: default

steps:
- name: fetch
  image: alpine/git
  commands:
  - git fetch --tags

- name: build
  image: golang
  commands:
  - go build
  - go test

The --recursive flag

The default clone behavior does not use the --recursive flag and does not fetch submodules. If you would like to fetch submodules you should handle this as a step in your pipeline. For example:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
16

kind: pipeline
type: kubernetes
name: default

steps:
- name: submodules
  image: alpine/git
  commands:
  - git submodule init
  - git submodule update --recursive --remote

- name: build
  image: golang
  commands:
  - go build
  - go test

Custom Logic

The default clone behavior can be disabled and custom clone logic implemented, when necessary. In the following example we implement custom clone commands as a pipeline step:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
16
17
18
19

kind: pipeline
type: kubernetes
name: default

clone:
  disable: true

steps:
- name: clone
  image: alpine/git
  commands:
  - git clone https://github.com/octocat/hello-world.git .
  - git checkout $DRONE_COMMIT

- name: build
  image: golang
  commands:
  - go build
  - go test
