JDBetteridge/Composite actions by JDBetteridge · Pull Request #2868 · devitocodes/devito

JDBetteridge · 2026-03-06T23:50:18Z

Create composite actions for executing Docker things in workflows.

Makes stuff more consistent

The following workflows were renamed to be more descriptive/consistent:

pytest-mpi (gcc) → pytest-mpi (pytest-mpi-docker-gcc)
pytest-mpi (icx) → pytest-mpi (pytest-mpi-docker-icx)

Which needs updating in the repo settings

.github/actions/docker-clean/action.yaml

+  uid:
+    description: "Unique identifier output from docker-build action"
+    required: true
+  tag:


I pass both uid and tag everywhere, should these be combined into a single output from build and single input for clean and run? A unique_tag?

.github/actions/docker-run/action.yaml

+    required: true
+  command:
+    description: "Command to execute inside of the docker container"
+    required: true


A limitation of this approach is that only one command can be run in a container at once, making the workflows a little verbose in some places.

Might as well correct grammar on this comment

All your base are belong to us

Showing your advanced age there...

Looks great, thanks a lot!!

Left a bunch of generic comments that aren't strong change requests. Do those action files really need to be in three different directories? Why not just .github/actions/docker for all

.github/workflows/tutorials.yaml

+    strategy:
+      # Prevent cancellation if a single workflow fails
+      fail-fast: false
+      matrix:


It's a single entry, can drop the matrix and just put the values where needed, e.g

tutorials-docker: name: tutos-docker-gcc-py310 runs-on: $ubuntu-latest

and so on

I agree, but I was also going to raise the possibility of testing with some newer compilers in the next dev meeting, so I left it like this to be extensible (and consistent)

.github/workflows/tutorials.yaml

JDBetteridge · 2026-03-20T13:40:48Z

.github/workflows/pytest-core-mpi.yaml

+    - id: build
+      name: Build docker image
+      uses: ./.github/actions/docker-build
+      with:
+        file: docker/Dockerfile.devito
+        tag: ${{ matrix.name }}
+        base: devitocodes/bases:cpu-${{ matrix.arch }}


@mloubout here we don't use base

Sadly yes, you cannot use them otherwise 😞
