How to know which node:alpine image version is in running container

Time:07-27

I have one running container which uses node:alpine as base image.I want to know version of this image.

CodePudding user response:

Try running the command node:<version>-alpine

You can also try running the command alpine -v or alpine -version .You can also start Alpine and press? on the main menu to open the main Help page, which will also tell you the version.

CodePudding user response:

You can check the Dockerfile of the container if handy.

You can check the first line with FROM node:<version>-alpine

For example :

FROM node:12.18.1-alpine
ENV NODE_ENV=production
WORKDIR /app

You can also use the command docker image inspect

https://docs.docker.com/engine/reference/commandline/image_inspect/

You can also exec into the container to check the version of Node

Command to check node version:

docker exec -ti <Container name> sh -c "node --version"
