comando docker non trovato anche se installato con apt-get

Question

Aggiungendo questo per riferimento per gli altri perché mi avrebbe salvato 10 minuti se tale risposta esisteva.

Ho provato a installare Docker usare Ubuntu 14.0LTS virtualbox

sudo apt get install docker

Tuttavia, quando provo correre finestra mobile mi dà il seguente errore

The program 'docker' is currently not installed. You can install it by typing: sudo apt-get install docker

Perché è Ubuntu non vedere la finestra mobile?

Answer 1

Il pacchetto Ubuntu docker si riferisce in realtà a un'applicazione GUI, non all'apprezzato strumento DevOps che abbiamo cercato.

=== AGGIORNATO (grazie @ Scott Stensland) ===

A questo punto eseguire il seguente script di installazione per ottenere finestra mobile:

sudo curl -sSL https://get.docker.com/ | sh 

Ciò eseguire uno script che installa finestra mobile. Si noti l'ultima parte dello script:

If you would like to use Docker as a non-root user, you should now consider 
adding your user to the "docker" group with something like: 

    sudo usermod -aG docker stens 

Remember that you will have to log out and back in for this to take effect! 

Per aggiornare eseguire Docker:

sudo apt-get update && apt-get upgrade 

Per maggiori dettagli su quello che sta succedendo, Vedere la docker install documentation o la risposta di @ Scott Stensland sotto

= == RISPOSTA OSSOLETA ===

Invece di utilizzare docker utilizzare docker.io

cioè,

sudo apt-get install docker.io

Di seguito viene spiegato il motivo per cui è chiamato in questo modo: Why install docker on ubuntu should be `sudo apt-get install docker.io`?

Answer 2

IMPORTANTE - il pacchetto ubuntu docker è qualcosa di completamente diverso (evitarlo):

apt-cache search ^docker$ 

docker - System tray for KDE3/GNOME2 docklet applications 

NOTA - il pacchetto ubuntu docker.io non riceve l'aggiornamento Ates (obsoleti non uso)

---

Invece fare questo: installare l'ultima versione di finestra mobile su Linux eseguendo il seguente:

sudo curl -sSL https://get.docker.com/ | sh 
# sudo curl -sSL https://test.docker.com | sh # get dev pipeline version 

ecco un output tipico (ubuntu 16 .04)

apparmor is enabled in the kernel and apparmor utils were already installed

Ecco il sottostante dettagliato istruzioni di installazione che come potete vedere viene impacchettato in tecnica di cui sopra ... Sopra uno di linea ti dà uguale:

https://docs.docker.com/engine/installation/linux/ubuntulinux/

Una volta installato è possibile visualizzare i pacchetti finestra mobile sono stati installati mediante l'emissione di

dpkg -l|grep docker 

ii docker-engine        1.11.2-0~xenial          amd64  Docker: the open-source application container engine 

ora otterrà installato gli aggiornamenti docker andando avanti quando yo u emettere

sudo apt-get upgrade

Answer 3

sudo apt-get install docker 

è una libreria diversa su Ubuntu.

Utilizzare sudo apt-get install docker.io per installare la finestra mobile corretta.

Answer 4

impostare il REPOSITORY

Per Ubuntu 14.04/16.04/16.10/17.04:

sudo add-apt-repository "deb [arch=amd64] \ 
    https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" 

Per Ubuntu 17.10:

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu zesty stable" 

Aggiungi chiave GPG ufficiale di Docker:

$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add - 

quindi installare

$ sudo apt-get update && sudo apt-get -y install docker-ce 

Answer 5

eseguire il comando Docker con sudo:

sudo docker <your command> 

Come il documentation dice:

La finestra mobile daemon si lega ad un socket Unix, invece di una porta TCP. Di default il socket Unix è di proprietà dell'utente root e gli altri utenti possono accedervi solo usando sudo. Il daemon docker viene sempre eseguito come utente root.

Se non si desidera utilizzare sudo quando si utilizza il comando finestra mobile, creare un gruppo Unix chiamato finestra mobile e aggiungere utenti ad esso. Quando il daemon docker viene avviato, rende la proprietà del socket Unix in lettura/scrittura dal gruppo di finestre mobili .
