[Drone CI](https://drone.io/) is a free and open-source continuous integration platform and allows running tests for Julia packages on ARM architecture. You can install a local instance of Drone or use Drone Cloud at [https://cloud.drone.io/](https://cloud.drone.io/) Documentation of Drone is at [https://docs.drone.io/](https://docs.drone.io/).
The `.drone.yml` script to add to the top-directory of your repository to run tests looks like the following:
```yaml
---
kind: pipeline
name: linux - arm - Julia 1.0
platform:
os: linux
arch: arm
steps:
- name: build
image: julia:1.0
commands:
- "julia --project=. --check-bounds=yes --color=yes -e 'using InteractiveUtils; versioninfo(verbose=true); using Pkg; Pkg.build(); Pkg.test(coverage=true)'"
---
kind: pipeline
name: linux - arm - Julia 1.1
platform:
os: linux
arch: arm
steps:
- name: build
image: julia:1.1
commands:
- "julia --project=. --check-bounds=yes --color=yes -e 'using InteractiveUtils; versioninfo(verbose=true); using Pkg; Pkg.build(); Pkg.test(coverage=true)'"
---
kind: pipeline
name: linux - arm64 - Julia 1.0
platform:
os: linux
arch: arm64
steps:
- name: build
image: julia:1.0
commands:
- "julia --project=. --check-bounds=yes --color=yes -e 'using InteractiveUtils; versioninfo(verbose=true); using Pkg; Pkg.build(); Pkg.test(coverage=true)'"
---
kind: pipeline
name: linux - arm64 - Julia 1.1
platform:
os: linux
arch: arm64
steps:
- name: build
image: julia:1.1
commands:
- "julia --project=. --check-bounds=yes --color=yes -e 'using InteractiveUtils; versioninfo(verbose=true); using Pkg; Pkg.build(); Pkg.test(coverage=true)'"
...
```
The YAML script doesn’t support a matrix, like Travis does, to easily setup different jobs for different architectures and/or Julia versions, however it’s possible to write a simple [Jsonnet](https://jsonnet.org/) script from which the full YAML can be automatically generated. For example, I generated the above YAML script from this Jsonnet script:
```json
local Pipeline(os, arch, version) = {
kind: "pipeline",
name: os+" - "+arch+" - Julia "+version,
platform: {
os: os,
arch: arch
},
steps: [
{
name: "build",
image: "julia:"+version,
commands: [
"julia --project=. --check-bounds=yes --color=yes -e 'using InteractiveUtils; versioninfo(verbose=true); using Pkg; Pkg.build(); Pkg.test(coverage=true)'"
]
}
]
};
[
Pipeline("linux", "arm", "1.0"),
Pipeline("linux", "arm", "1.1"),
Pipeline("linux", "arm64", "1.0"),
Pipeline("linux", "arm64", "1.1")
]
```
While it’s possible to directly use the Jsonnet script in a local instance of Drone (see, e.g., [Porting matrix builds to 1.0 multi-machine pipelines - FAQ - Drone](https://discourse.drone.io/t/porting-matrix-builds-to-1-0-multi-machine-pipelines/2966)), this feature is not supported by Drone Cloud (see [Drone Cloud and jsonnet? - Drone](https://discourse.drone.io/t/drone-cloud-and-jsonnet/4621)), so if you want to use this service you have to manually generate the YAML file and have it in your repository. See [here](https://docs.drone.io/cli/install/) how to download and install the [Drone command line utility](https://github.com/drone/drone-cli). Once you get it, you can generate the `.drone.yml` script with
```nohighlight
drone jsonnet --stream .drone.jsonnet
```

Just one additional note, that tags for pre-release ARM builds can be found over at [Docker Hub](https://hub.docker.com/_/julia?tab=tags)

And another, [gcc/g++ aren’t installed in the arm images](https://github.com/docker-library/julia/issues/13), but can be added with:
```julia
kind: pipeline
name: linux-arm-1.3-RC2
platform:
os: linux
arch: arm
steps:
- name: build
image: julia:1.3.0-rc2
commands:
- uname -a
- apt-get update
- apt-get install -y gcc g++
- julia --project=. -e 'using Pkg; Pkg.build(); Pkg.test(coverage=true)'
```
