Get Python und reagieren Komponente basierte Container zu arbeiten

Question

Ich versuche, diesen Workflow von isomorphic app dockerisieren. Ich baue den Container der unteren Docker-Datei.

FROM python:3.5-slim 

RUN apt-get update && \ 
    apt-get -y install gcc mono-mcs && \ 
     apt-get -y install vim && \ 
     apt-get -y install nano && \ 
      rm -rf /var/lib/apt/lists/* 

RUN mkdir -p /statics/js 

VOLUME ["/statics/"] 

WORKDIR /statics/js 

COPY requirements.txt /opt/requirements.txt 

RUN pip install -r /opt/requirements.txt 

EXPOSE 8080 

CMD ["python", "/statics/js/app.py"] 

und dies war das Ergebnis:

$ docker build -t ciasto/pythonreact:v2 .

Also meine erste Frage ist, was die Stufe 9 Mittel tut? bedeutet das, dass es versucht, den /statics/js/app.py Pfad noch vor dem Ausführen des Containers auszuführen, da das nicht funktionieren würde, da ich plante, dieses statics Volume von der host zu mounten. Zweitens, wenn ich den Befehl ausführen:

$ docker run -it -v ~/Development/my-Docker-builds/pythonReact/statics/:/statics/ -d ciasto/pythonreact:v2 

03d77c87651e752450e3be0aa64a0841c088b32a1db5424ad96c150c949d0366

ich die Raute-Taste, aber nichts funktioniert! Ich sehe nicht einmal die Start-Trace oder Fehlermeldung von app.py hatte einen Fehler.

Also wie sollte ich die app.py von Host montierten Volume ausführen, wenn ich den Container ausführen?

Answer 1

Sie können CMD als Startskript für den Container betrachten. Nachdem Sie gesagt haben, dass in Schritt 9 nur pyhton /statics/js/app.py markiert ist, wird es ausgeführt, wenn Sie den Container starten. da Sie -d Flagge Auch verwenden, werden Sie nicht in der Lage sein, Protokolle, um zu sehen, so dass Sie sie mit docker logs Befehl zu holen haben, wie:

docker logs 03d77c87651e752450e3be0aa64a0841c088b32a1db5424ad96c150c949d0366 

Die Protokolle genug sein, sollten Sie das Problem helfen herauszufinden. Ich hoffe, es hilft.
