File not found exception while running DockerFile

Question

Here my DockerFile :-

FROM openjdk:10
ENV AQUILA_HOME /data/config
#USER root
#VOLUME /tmp
ADD a2i-web-1.0.0-SNAPSHOT.jar app.jar
#RUN bash -c 'touch /app.jar'
ENTRYPOINT ["java","-jar","app.jar"]

My jar is spring boot application which refers configuration file from some directory [/data/config/config.properties] I am building DockerFile successfully by command

sudo docker build -t dockImgName/a2i-web:v1 .

But while running it by command

sudo docker run -p 8080:8080 -t dockImgName/a2i-web:v1

giving exception as :

Caused by: java.io.FileNotFoundException: /data/config/config.properties (No such file or directory)

I am running this dcoker command from directory containing DockerFile and my jar Do I need to set any configuration to get config file directory?

Answer 1

The error message is quite clear. When the container tries to run it is not able to find properties file.

You need to add config.properties file to your docker image.

ADD path_to_config_file/config.properties /data/config/config.properties

NOTE: path_to_config_file refers to the file path in your local where you are building the dockerfile
