Installa pip nella finestra mobile

Question

Non riesco a installare pip in Docker.

Ecco la mia Dockerfile:

FROM ubuntu:14.04 

# Install dependencies 
RUN apt-get update -y 
RUN apt-get install -y git curl apache2 php5 libapache2-mod-php5 php5-mcrypt php5-mysql python3.4 python-pip 

Quando si costruisce, ottengo:

Letta this answer, ho provato ad aggiungere la linea RUN "sh" "-c" "echo nameserver 8.8.8.8 >> /etc/resolv.conf" - l'errore questa volta è:

Cosa sto sbagliando? Ho visto alcune affermazioni che dovrei provare una versione diversa di Ubuntu, ma passare a 13.1 non ha cambiato nulla.

Answer 1

Mentre la risposta di T. Arboreus potrebbe risolvere i problemi con la risoluzione di 'archive.ubuntu.com', penso che l'ultimo errore che si sta dicendo dice che non sa sui pacchetti php5-mcrypt e python-pip. Tuttavia, il Dockerfile ridotto di te con solo questi due pacchetti ha funzionato per me (usando Debian 8.4 e Docker 1.11.0), ma non sono sicuro che questo potrebbe essere il caso perché il mio sistema host è diverso dal tuo.

FROM ubuntu:14.04 

# Install dependencies 
RUN apt-get update && apt-get install -y \ 
    php5-mcrypt \ 
    python-pip 

Tuttavia, secondo this answer si dovrebbe pensare di installare il pacchetto python3-pip invece del pacchetto python-pip quando si usa Python 3.x.

Inoltre, per rendere operativa l'installazione del pacchetto php5-mcrypt, è possibile aggiungere il repository universe come mostrato in right here. Ho avuto problemi con il comando add-apt-repository mancante nell'immagine di Ubuntu Docker quindi ho installato il pacchetto software-properties-common all'inizio per rendere disponibile il comando.

È anche consigliabile dividere le istruzioni e inserire apt-get update e apt-get install in un comando RUNhere.

Oh, a proposito, in realtà non è necessario il flag -y allo apt-get update perché non c'è nulla che debba essere confermato automaticamente.

Infine:

FROM ubuntu:14.04 

# Install dependencies 
RUN apt-get update && apt-get install -y \ 
    software-properties-common 
RUN add-apt-repository universe 
RUN apt-get update && apt-get install -y \ 
    apache2 \ 
    curl \ 
    git \ 
    libapache2-mod-php5 \ 
    php5 \ 
    php5-mcrypt \ 
    php5-mysql \ 
    python3.4 \ 
    python3-pip 

Nota: Le versioni utilizzate (ad esempio di Ubuntu) potrebbero essere superate in futuro.

Answer 2

Prova questo:

1. Rimuovere il commento dalla riga seguente in/etc/default/docker DOCKER_OPTS = "- dns 8.8.8.8 8.8.4.4 --dns"
2. Riavviare il Servizio sudo Docker docker restart
3. Elimina le immagini che hanno memorizzato nella cache le impostazioni DNS non valide.
4. Compilare nuovamente e il problema dovrebbe essere risolto.

Da this question.
