How to run sql script before the application launches in docker - entity-framework

Question

I'm deploying the project with Asp.net Core, PostgreSql and Docker in Windows 10 (no PostgreSql installed). So I have to run sql script to update data before the application launches (for registering a singleton dependency injection).
The content of my Dockerfile as following:
# TODO use official docker image
FROM microsoft/dotnet:1.1.0-sdk-projectjson
# Install .NET CLI dependencies
RUN apt-get update && apt-get install -y --no-install-recommends \
autoconf \
automake \
bzip2 \
file \
g++ \
gcc \
imagemagick \
libbz2-dev \
libc6-dev \
libcurl4-openssl-dev \
libdb-dev \
libevent-dev \
libffi-dev \
libgdbm-dev \
libgeoip-dev \
libglib2.0-dev \
libjpeg-dev \
libkrb5-dev \
liblzma-dev \
libmagickcore-dev \
libmagickwand-dev \
libmysqlclient-dev \
libncurses-dev \
libpng-dev \
libpq-dev \
libreadline-dev \
libsqlite3-dev \
libssl-dev \
libtool \
libwebp-dev \
libxml2-dev \
libxslt-dev \
libyaml-dev \
make \
patch \
xz-utils \
zlib1g-dev \
&& rm -rf /var/lib/apt/lists/*
# Set environment variables
ENV ASPNETCORE_URLS="http://*:5000"
ENV ASPNETCORE_ENVIRONMENT="Development"
# Copy files to app directory
COPY . /app
# Set working directory
WORKDIR /app
# Restore NuGet packages
RUN ["dotnet", "restore"]
# Build app
RUN ["dotnet", "build"]
#dotnet ef migrations add InitialCreate
RUN ["dotnet", "ef", "migrations", "add", "InitialCreate"]
# Open up port
EXPOSE 5000
CMD chmod +x ./docker-start.sh
CMD bash ./docker-start.sh
And here is the content of docker-start.sh:
#!/bin/bash
set -e
# How to apply migrations
dotnet ef database update
# I would like to run sql file at here"
psql -h postgres --username postgres -d POSTGRES_USER -a -f /app/static.sql
# Start web app
echo "Starting web app"
dotnet run
How can I do that? Thanks advanced.

Answer 1

I have just found a solution for this. I missed postgresql-client. We will be need to install postgresql-client as using psql to run the sql script from Dockerfile.
So Dockerfile should be changed:
# TODO use official docker image
FROM microsoft/dotnet:1.1.0-sdk-projectjson
# Install .NET CLI dependencies
RUN apt-get update && apt-get install -y --no-install-recommends \
autoconf \
automake \
bzip2 \
file \
g++ \
gcc \
imagemagick \
libbz2-dev \
libc6-dev \
libcurl4-openssl-dev \
libdb-dev \
libevent-dev \
libffi-dev \
libgdbm-dev \
libgeoip-dev \
libglib2.0-dev \
libjpeg-dev \
libkrb5-dev \
liblzma-dev \
libmagickcore-dev \
libmagickwand-dev \
libmysqlclient-dev \
libncurses-dev \
libpng-dev \
libpq-dev \
libreadline-dev \
libsqlite3-dev \
libssl-dev \
libtool \
libwebp-dev \
libxml2-dev \
libxslt-dev \
libyaml-dev \
make \
patch \
xz-utils \
zlib1g-dev \
postgresql-client \
&& rm -rf /var/lib/apt/lists/*
# Install netcat so that we can ping the database server until it
RUN apt-get update -qq \
&& apt-get install -y netcat \
&& rm -rf /var/lib/apt/lists/*
# Set environment variables
ENV ASPNETCORE_URLS="http://*:5000"
ENV ASPNETCORE_ENVIRONMENT="Development"
ENV DB_HOSTNAME="posgres"
# Copy files to app directory
COPY . /app
# Set working directory
WORKDIR /app
# Restore NuGet packages
RUN ["dotnet", "restore"]
# Build app
RUN ["dotnet", "build"]
#dotnet ef migrations add InitialCreate
RUN ["dotnet", "ef", "migrations", "add", "InitialCreate"]
# Open up port
EXPOSE 5000
CMD chmod +x ./docker-start.sh
CMD bash ./docker-start.sh
Thanks.
