mkdkr = Makefile + Docker
Super small and powerful framework for build CI pipeline, scripted with Makefile and isolated with docker.
- Dependencies: [ make, docker, bash, git ]
- Two files only (Makefile and .mkdkr), less garbage on your repo
- All power of make, docker and bash
- Shipping and switch among CI engines like Circle CI, GitHub Actions, Gitlab-ci, Jenkins, Travis.. and more using exporter
- Clean and elegant code syntax
Create a file with name Makefile and paste the following content.
Download .mkdkr
dynamically.
# Required header
include $(shell [ ! -f .mkdkr ] && curl -fsSL https://git.io/JOBYz > .mkdkr; bash .mkdkr init)
# without shorten url
# include $(shell [ ! -f .mkdkr ] && curl -fsSL https://github.com/rosineygp/mkdkr/releases/latest/download/mkdkr > .mkdkr; bash .mkdkr init)
job:
@$(dkr)
instance: alpine
run: echo "hello mkdkr dynamic!"
OR keep .mkdkr
locally.
# Download .mkdkr
curl -fsSL https://github.com/rosineygp/mkdkr/releases/latest/download/mkdkr > .mkdkr
# Required header
include $(shell bash .mkdkr init)
job:
@$(dkr)
instance: alpine
run: echo "hello mkdkr local!"
.gitignore (optional)
.tmp
.mkdkr # only in dynamic config
# execute
make job
start: job
instance: alpine

hello mkdkr!

Run your current Makefile in another engine, like travis or github actions, use the dynamic include exporter.

Build pipeline for a dedicated platform can take a lot of time to learn and test, with mkdkr you can test all things locally and run it in any pipeline engine like Jenkins, Actions, Gitlab-ci and others.
Load docker layer for mkdkr, use inside a target of Makefile.
shell-only:
echo "my local shell job"
mkdkr-job:
@$(dkr) # load all deps of mkdkr
intance: alpine
run: echo "my mkdkr job"
Create docker containers, without special privileges.
my-instance:
@$(dkr)
instance: ubuntu:20.04 # create a instance
Parameters:
- String, DOCKER_IMAGE *: any docker image name
- String|Array, ARGS: additional docker init args like (--cpus 1 --memory 64MB)
Return:
- String, Container Id
Calling instance: twice, it will replace the last container.
Create a docker container in detached mode. Useful to bring up a required service for a job, like a webserver or database.
my-service:
@$(dkr)
service: nginx # up a nginx
instance: alpine
Is possible start more than one service.
multi-service:
@$(dkr)
service: mysql
service: redis
instance: node:12
run: npm install
run: npm test
* Instance and services are connected in same network
** The name of service is the same of image name with safe values
Image Name | Network Name |
---|---|
nginx | nginx |
nginx:1.2 | nginx_1_2 |
redis:3 | redis_3 |
project/apache_1.2 | project_apache_1_2 |
registry/my/service:latest | registry_my_service_latest |
replace role
's/:|\.|\/|-/_/g'
Parameters:

Is possible create jobs or fragments of jobs and reuse it in another projects, like a code package library.
There are two major behavior of includes:
A fragment of job (eg. define
) and needs to be called explicitly to work.
TAG=latest
define docker_build =
@$(dkr)
dind: docker:19
run: docker build -t $(REGISTRY)/$(PROJECT)/$(REPOS):$(TAG) .
endef
All definitions will be load at start of makefile, after it is possible to call at your custom job.
my-custom-build:
$(docker-build)
Just a full job in another project.
TAG=latest
docker_build:
@$(dkr)
dind: docker:19
run: docker build -t $(REGISTRY)/$(PROJECT)/$(REPOS):$(TAG) .
The jobs will be load at start and can be called directly.
make docker_build
- No needs to implement the job at main Makefile.
- Very useful for similar projects.
A file with name mkdkr.csv
, that contains the list of remote includes.
Needs to be at same place o main Makefile.
