Hi Guys,

So i decided to move away from the pipeline exec type and work with docker style pipelines. The syntax is nearly the same; however, a challenge at first was how to do some basic linux command stuff on the host ec2 instance. Nonetheless, I finally figured it out.. dah.. rsync!

Anyhow, this is a general script i wrote that does several things: 1) install dependencies via composer; 2) install dependencies via yarn; 3) rsync into host and move stuff around and fix permissions etc; 4) tarball; 5) upload to s3; 6) email.

note To use docker pipelines you need to run the docker runner. Because i also use exec pipelines you need to configure the port to something other than 3000.

docker run -d \
-v /var/run/docker.sock:/var/run/docker.sock \
--env-file=/var/drone.env \
-e DRONE_RUNNER_NAME=${HOSTNAME} \
-p 4000:4000 \
--restart always \
--name runner \
drone/drone-runner-docker:1

while drone should run as

docker run \
--volume=/var/run/docker.sock:/var/run/docker.sock \
--volume=/var/lib/drone:/data \
--env-file=/var/drone.env \
--publish=40080:80 \
--publish=40443:443 \
--restart=always \
--detach=true \
--name=drone \
drone/drone:1
