How to setup a older meteor version in dockerfile, and docker container - docker

Question

I have a project running with meteor and node.js in my local. The meteor version is 2.4, node.js version is 8.9.4, I have meteor/release file to make meteor version be 2.2 so that meteor and node can work together.
(base) xxx$ meteor --version
Meteor 2.4
(base) xxx$ node -v
v8.9.4
It seems fine so I deploy this project to docker container to server. The Dockerfile first line I wrote
# node version dependent on meteor version
FROM node:8.9.4
After successfully deployed, the docker logs shows error siad.
Waiting for mongodb server to start - sleeping
warn: --minUptime not set. Defaulting to: 1000ms
warn: --spinSleepTime not set. Your script will exit if it does not stay up for at least 1000ms
info: Forever processing file: /app/bundle/main.js
error: undefined
data: /app/bundle/main.js:34 - Meteor requires Node v12.0.0 or later.
data: /app/bundle/main.js:34 - error: Forever detected script exited with code: 1
I check inside docker, the node version is 8.9.4
(base) [xxx]$ docker exec -it -u root tblbuilder_meteor_1 /bin/bash -c 'node --version'
v8.9.4
So I assume it is meteor version. But first I dont know how to check meteor version inside the docker. And second why this happens? I am sure the release file is updated to push project folder.
With some great man help, I kinda understand it. In local I use meteor 2.2, in docker file I use node.js 8.9.4 work with meteor2.2. So the thing I left is to modify DOCKERFILE, change it from node 8.9.4 to node 12. Below is my Dockerfile file, I try to change it to node 12.22.2, but it keep give me error, I spent one day to solve them. Currently, I stack at install r-base part.
Is there some guide for change node 8 to node 12.
# node version dependent on meteor version
FROM node:8.9.4
# I am going to use 12.22.2
#FROM node:12.22.2
# (even if copied as root you still need to change)

Answer 1

There are many wrong understanding in your tests:
Your Meteor version is 2.2, because is the version inside your project;
To you see the Node version of this Meteor project, see this answers that many guys send to you in Meteor Docker Node.js version is not match
Usually, we build the Meteor, that mean transform it in a NodeJS package build, then, inside of the Docker you don't need Meteor.
We need see your Dockerfile and understand what process you do to build do Docker image.
