Heroku [=h10=] 成功后出现错误 运行 heroku container:push web 和 heroku container:release web
Heroku "Missing required flag -a --app" error after succesfully running heroku container:push web and heroku container:release web
我有一个 Docker 容器，我正尝试将其部署为 Heroku 应用程序。我的应用程序名为
morning-bayou-58742
之前我运行成功执行了以下命令
heroku container:login
heroku create
heroku container:push web --app morning-bayou-58742
heroku container:release web --app morning-bayou-58742
后者的输出为
Releasing images web to morning-bayou-58742... done
然而，当我打开我的网络应用程序时，出现以下错误
Application error
An error occurred in the application and your page could not be
served. If you are the application owner, check your logs for details.
You can do this from the Heroku CLI with the command heroku logs
--tail
当我检查日志尾部时，我得到以下内容
heroku logs --tail
» Error: Missing required flag: » -a, --app APP app to run
command against » See more help with --help
现在我尝试做的是尝试 运行 来自 Heroku https://devcenter.heroku.com/articles/container-registry-and-runtime#getting-started 的入门文档，它是这样的：
heroku container:login
git clone https://github.com/heroku/alpinehelloworld.git
heroku create
heroku container:push web
heroku container:release web
heroku open
而且效果很好！所以我现在更糊涂了。你能提供一些关于问题可能是什么的提示吗？以防万一，这是我的 Docker 容器结构，当我 运行 使用 localhost:
时它工作正常
app.py:
#my libraries
import pickle
import numpy as np
import sys
import os
from sklearn.neighbors import KNeighborsClassifier
from flask import Flask, request
#set port
port = int(os.environ.get("PORT", 5000))
#open model back
with open('./model.pkl', 'rb') as model_pkl:
knn = pickle.load(model_pkl)
knn.n_jobs=1
#flask application
app = Flask(__name__)
#API endpoint
@app.route('/predict')
def predict_iris():
#retrieve parameters
sl = float(request.args.get('sl'))
sw = float(request.args.get('sw'))
pl = float(request.args.get('pl'))
pw = float(request.args.get('pw'))
#predict result
new_record = np.array([[sl, sw, pl, pw]])
print(new_record)
predict_result = knn.predict(new_record)[0]
#label classes
classes=['setosa', 'versicolor', 'virginica']
#encode result
if predict_result==0:
result=classes[0]
elif predict_result==1:
result=classes[1]
elif predict_result==2:
result=classes[2]
else:
print("nothing to show")
#return result
return "Prediction is: " + str(result)
if __name__ == '__main__':
app.run(debug=True,host='0.0.0.0',port=port)
Docker文件:
FROM python:3.5.3
COPY . /app
WORKDIR /app
RUN pip install -r requirements.txt
EXPOSE 5000
ENTRYPOINT python ./app.py
Requirements.txt:
numpy==1.13
scipy==0.19.1
Flask==0.12.2
scikit-learn==0.18.1
我的 Docker 容器称为 flask-heroku-bis，我 运行 使用命令
docker run -d -p 5000:5000 flask-heroku-bis
然后我在输入本地 url 调用时得到结果，例如 http://localhost:5000/predict?sl=100.2&sw=11.7&pl=10.8&pw=3
我认为问题可能与此调用的结构有关，但我不是 100% 确定。
感谢任何帮助！

由于您没有详细的日志文件，这里很难排除故障。您可以先尝试执行此操作以查明确切的问题：
heroku logs --tail -a morning-bayou-58742
接下来，尝试使用命令 heroku open 访问您已部署的应用程序，以防万一 url.
有任何拼写错误
编辑：
由于 Heroku 中的网络限制，Dockerfile 中的 EXPOSE 不受支持，Heroku 需要 CMD 才能 运行 容器。基于 Flask 的示例应用程序可以这样启动 (reference):
FROM python:3.5.3
COPY . /app
WORKDIR /app
RUN pip install -r requirements.txt
# Expose is NOT supported by Heroku
# EXPOSE 5000
# Run the app. CMD is required to run on Heroku
# $PORT is set by Heroku
CMD gunicorn --bind 0.0.0.0:$PORT wsgi

由于您没有详细的日志文件，这里很难排除故障。您可以先尝试执行此操作以查明确切的问题：
heroku logs --tail -a morning-bayou-58742
接下来，尝试使用命令 heroku open 访问您已部署的应用程序，以防万一 url.
编辑：
由于 Heroku 中的网络限制，Dockerfile 中的 EXPOSE 不受支持，Heroku 需要 CMD 才能 运行 容器。基于 Flask 的示例应用程序可以这样启动 (reference):
FROM python:3.5.3
COPY . /app
WORKDIR /app
RUN pip install -r requirements.txt
# Expose is NOT supported by Heroku
# EXPOSE 5000
# Run the app. CMD is required to run on Heroku
# $PORT is set by Heroku
CMD gunicorn --bind 0.0.0.0:$PORT wsgi
