hello world



nicholas@mordor:~/html$ 

Non sono chiaro l'origine e la destinazione, il che potrebbe essere complicato dockeressendo stato installato da snap.

Sembra che ansibleabbia una sintassi leggermente più chiara, almeno per me:

  tasks:
  - name: "Copying files"
    copy:
      src: files/{{ item }}
      dest: /my/folder/
    with_items:
      - file.txt

o forse sto facendo qualcosa di sbagliato.

Answer 1

The docker build command builds Docker images from a Dockerfile and a “context”. A build’s context is the set of files located in the specified PATH or URL. The build process can refer to any of the files in the context. For example, your build can use a COPY instruction to reference a file in the context.

Dalla documentazione di build docker .

Mentre esegui la build docker con il .percorso per il contesto, cercherà di trovare la cartella home/nicholas/htmldal contestoroot@mordor:/home/nicholas/docker/nginx

La documentazione del comando COPY mostra alcuni esempi

Answer 2

Questo almeno costruisce ed esegue:

root@mordor:/home/nicholas/docker/nginx# 
root@mordor:/home/nicholas/docker/nginx# ls -al
total 16
drwxrwxr-x 2 nicholas nicholas 4096 Nov 13 17:18 .
drwxrwxr-x 3 nicholas nicholas 4096 Nov 13 16:12 ..
-rw-rw-r-- 1 nicholas nicholas   49 Nov 13 17:18 dockerfile
-rw-rw-r-- 1 nicholas nicholas   56 Nov 13 17:18 index.html
root@mordor:/home/nicholas/docker/nginx# 
root@mordor:/home/nicholas/docker/nginx# cat dockerfile 
FROM nginx
COPY index.html /usr/share/nginx/html
root@mordor:/home/nicholas/docker/nginx# 
root@mordor:/home/nicholas/docker/nginx# cat index.html 



hello world

how do I put this file in a diff dir?

anche se non riesco a ottenere nulla dalla navigazione a, localhostquindi dovrò guardare più da vicino al containerquale è costruito.
