#docker (2019-06)

hello everyone, I have a question about npm install -> postinstall inside docker I have super small config (exmple)

{
  "private": true,
  "scripts": {
    "postinstall": "echo test"
  }
}

when I execute npm i --unsafe-perm everything goes well but when I execute npm ci --unsafe-perm I’ve got error message npm ERR! Cannot read property 'length' of undefined

does anybody know what to do?

Have you tried building the container without running this command in the Dockefile. Then start the container with a shell, and triage that way? Sometimes it’s easier to understand what is going on

hmmm

no

I’ve tried. - the same error

Step 5/7 : RUN npm ci --unsafe-perm
 ---> Running in 8781a79481f0
npm ERR! Cannot read property 'length' of undefined

npm ERR! A complete log of this run can be found in:
npm ERR!     /root/.npm/_logs/2019-06-01T19_33_54_463Z-debug.log

the problem is in postinstall

but I have no any idea what is wrong with npm ci and postinstall

seems like i found the reason!

npm 6.5.0 works

npm upper version doesn’t work

has anyone tried running a desktop on docker. Target is to deploy a virtual desktop solution using containers. Tried LXC containers, but had issues with the networking when the core server was deployed on cloud. Seems docker will be a better alternative, then again not easier to configure as a workstation like lxc/lxd.

how do you guys periodically update your docker images? looking moreso for automated solutions

What specifically is the objective?

Pull in latest packages?

docker watchtower

I guess @btai meant, maintaining, building and updating docker images (and push the new tagged release to a registry). Do you know any CI/CD examples for that purpose?

meant moreso fo rsecutity

i use codefresh for wut ur talking about
