for the docker imaging look at: https://www.fosstechnix.com/how-to-create-docker-image-for-node-js-application/
|
||||
The docker image can be built with
|
||||
docker build -t dumbserver .
|
||||
podman build -t dumbserver .
|
||||
|
||||
the image then can be extracted with
|
||||
docker image save -o dumbserver.image.tar dumbserver
|
||||
podman image save -o dumbserver.image.tar dumbserver
|
||||
|
||||
on the target machine it can be imported with
|
||||
docker image load -i dumbserer.image.tar
|
||||
podman image load -i dumbserer.image.tar
|
||||
|
||||
and running a container with the image id done via:
|
||||
docker run -p 1280:1280 dumbserver
|
||||
podman run --name dumbserver -p 1280:1280 dumbserver
|
||||
(Port 1280 is what it listens on)
|
||||
|
||||
updating the image from a local file (in podman):
|
||||
podman pull oci-archive:/tmp/dumbserver.image.tar
|
||||
then the container needs to be re-created... stop/rm/run
|
||||
|
||||
At this stage, terraform will create an ssh accessable server (key is in "terraformtest1.ppk") - tutorial used for that: https://medium.com/@hmalgewatta/setting-up-an-aws-ec2-instance-with-ssh-access-using-terraform-c336c812322f
|
||||
|
||||
As part of the terraform, I copy a script to install docker/podman - and upload the image
|
||||
then I set up the container and start it. that's it.
