You could use `apt-file search` to determine the command in which package. From my ubuntu16.04, it tells me to install `iproute2`, I think 1804 similar.

__1. Get what package need to be installed:__

    $ apt-file search --regexp &#39;bin/ip$&#39;
    iproute2: /bin/ip
    iproute2: /sbin/ip

__2. Install the package:__

    $ apt install -y iproute2
    ...

__3. Verify the package is installed:__

    $ dpkg -l iproute2
    ii  iproute2    4.3.0-1ubuntu3      amd64      networking and traffic control tools

Don&#39;t forget to install the iproute2

    apt install iproute2

And then you may use `ip` command.

Once you have created your docker with ubuntu latest or any of version image and crated a ubuntu container, you have to run your ubuntu container and install the following for the basic networking command,

    apt-get update

    apt-get upgrade

    apt-get install -y net-tools

    apt-get update


I am currently using Windows 10 with WSL Ubuntu 18.04 installed. I am trying to use WSL as the default terminal in WebStorm however, I am able to use the bash from WSL but the default directory would not be set to the default project location.

Does anyone know how to set this up correctly?

In Visual Studio Code I made some changes which I do not want to commit en sync yet. However, after my holiday, I want to sync the files from the server (changes from my colleagues). So In Visual Studio Code I want to do a sync.


I get a message &quot;Please clean your repository working tree before checkout&quot; 

What do I need to do to get the files of my colleagues without losing my own uncommitted changes?

I am just looking at docker images in https://hub.docker.com/_/node/

For every version, the images are categorized into Alpine, Jessie, Stretch, Buster etc. What&#39;s their meaning?

In Docker image names what is the difference between Alpine, Jessie, Stretch, and Buster?

If you use the Coreutils tail command in Linux, you have a -f option that lets you follow a log file from the log&#39;s current position (it does not go to the very beginning of the file and display everything).

Is this functionality available in docker logs without waiting for it to traverse the whole log?

I have tried:

    docker logs --since 1m somecontainer
and

    docker logs -f --since 1m somecontainer

It appears that it actually traverses the entire log file (which can take a long time) and then starts echoing to the screen once it reaches the time frame you specify.  

Is there a way to start tailing from the current point without waiting?
Is my best option to always log out to some external file and tail that with the Coreutils tail command?

Tail docker logs to see recent records, not all

In the Kubernetes [minikube tutorial][1] there is this command to use Minikube Docker daemon :

    $ eval $(minikube docker-env)

What exactly does this command do, that is, what exactly does `minikube docker-env` mean?

**TL;DR :** How can I pass env variable when building the image with `docker-compose` and have `docker run image command` recognize them ?

I have this Dockerfile :

    FROM mhart/alpine-node:10
    ADD . /app
    WORKDIR /app
    RUN apk --no-cache add --virtual builds-deps build-base python &amp;&amp;\
        yarn global add nodemon &amp;&amp;\
        yarn &amp;&amp;\
        apk del builds-deps build-base python

and this docker-compose.yml :

    version: &quot;3.3&quot;
    services:
    
      api:
        build:
          context: .
          dockerfile: Dockerfile-preprod
        image: registry.git.louis-girones.fr:4567/make-your-night/back:preprod
        environment:
          - NODE_ENV=development
        env_file:
          - .env
        volumes:
          - .:/app
        ports:
          - &quot;${PORT_PREPROD}:${PORT_PREPROD}&quot;
        command: sh -c &quot;mkdir -p dist &amp;&amp; touch ./dist/app.js &amp;&amp; yarn run start&quot;
    
      mongo:
        image: mongo:4.0
        ports:
          - &quot;${MONGO_PREPROD}&quot;
        command: mongod
        volumes:
          - ./data:/data/db
    
      elasticsearch:
        image: docker.elastic.co/elasticsearch/elasticsearch:6.1.1
        volumes:
          - ./esdata:/usr/share/elasticsearch/data
        environment:
          - bootstrap.memory_lock=true
          - &quot;ES_JAVA_OPTS=-Xms512m -Xmx512m&quot;
          - discovery.type=single-node
        ports:
          - &quot;9300:9300&quot;
          - &quot;9200:9200&quot;
    
    volumes:
      esdata:



With this .env file (which is in the root folder, like docker-compose.yml and Dockerfile) :

    #!/usr/bin/env bash

    NODE_ENV=development
    PORT=9000
    SECRET_SESSION=superSecr3t
    APP_NAME=Night Vision
    API_VERSION=/api/v0/
    DEFAULT_TZ=Europe/Paris
    ASSETS_URI=http://localhost:9000/public/img/
    BCRYPT_WORKFACTOR=1
    ES_PORT=9200
    ES_LOG_LEVEL=trace

And this code in the node server startup :

    // Export the config object based on the NODE_ENV
    // ==============================================
    const config: IConfig = commonConfig
    
    if (commonConfig.env === &#39;development&#39;) {
        _.merge(config, developmentConfig)
    } else if (commonConfig.env === &#39;test&#39;) {
        _.merge(config, testConfig)
    } else if (commonConfig.env === &#39;preproduction&#39;) {
        _.merge(config, preproductionConfig)
    } else if (commonConfig.env === &#39;production&#39;) {
        _.merge(config, productionConfig)
    } else {
        throw new Error(&#39;Please set an environment&#39;)
    }

When I run the `docker-compose build` command, everything is fine, but for instance If I try `docker run myimage yarn run test` the Error &quot;Please set an environment&quot; is thrown. 

I would expect that 

    env_file:
      - .env

makes the env variables of this file accessible in my image but that is not the case, that&#39;s why I tried to add 

     environment:
      - NODE_ENV=development

But still no success, I have also tried to pass my env variable as command line argument when I run the build :

`docker-compose build --build-arg  NODE_ENV=development api`

But it gives me this message :

    [Warning] One or more build-args [NODE_ENV] were not consumed
    Successfully built 9b14dd5abc3f


And I would really prefer to use the first or second methods

docker version : 18.06.1-ce
docker-compose version : 1.19.0

So Java 11 [is out][1]. Does anybody know how to install it (OpenJDK from Oracle) from the command line?

I would like to see something like it was before for Oracle Java 10:

    sudo add-apt-repository ppa:linuxuprising/java
    sudo apt-get update
    sudo apt-get install oracle-java10-installer

P. S. In the [similar][2] question proposed instruction:

    sudo apt-get install openjdk-11-jdk

doesn&#39;t work.

After freshly installing Ubuntu 18 I am receiving the following error when trying to launch a docker container that has a bind to a LVM (ext4) partition:

    mkdir /storage: read-only file system

I have tried reinstalling the OS, reinstalling Docker and forcing the drive to mount as RW (everything that isn&#39;t docker can write to the drive).

The directory that is being bound is currently set to 777 permissions.

There seems to be almost no information available for this error.

The Imagemagick security policy seems to be not allowing me perform this conversion from pdf to png. Converting other extensions seem to be working, just not from pdf. I haven&#39;t changed any of the imagemagick settings since I installed it... I am using Arch Linux, if the OS matters.

    user@machine $ convert -density 300 -depth 8 -quality 90 input.pdf output.png
    convert: attempt to perform an operation not allowed by the security policy `PDF&#39; @ error/constitute.c/IsCoderAuthorized/408.

my `yarn --version` is `0.32`. Why doesn&#39;t it work?

    ping: google.com: Temporary failure in name resolution
This problem is what&#39;s happing when trying to ping a domain instead of a IP, at this moment in the resolve.conf it has the 127.0.0.57 IP, tried adding this

    nameserver 8.8.8.8

and it fixed the problem on the short term, im going to be running a daemon that need to contact my domain control panel. so I need a long term solution.
If anyone has a solution to this issue it could be awesome.
