FileNotFound in docker environment

Hi,

I’ve some trouble with the de.flapdoodle.embed.mongo library in my Unit Tests. My Unit Tests are written in Java 8 using the Spring-Boot Framework in version 2.0.9.RELEASE. The embbeded mongodb is the suggested version from spring (2.0.3).

The unit tests runs on a jenkins using docker. The exception I have got is

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'embeddedMongoServer' defined in class path resource [org/springframework/boot/autoconfigure/mongo/embedded/EmbeddedMongoAutoConfiguration.class]: Invocation of init method failed; nested exception is java.io.IOException: Cannot run program "/tmp/extract-1aabfc01-694e-475b-b260-79d3c107a6d3extractmongod": error=2, No such file or directory
Caused by: java.io.IOException: Cannot run program "/tmp/extract-1aabfc01-694e-475b-b260-79d3c107a6d3extractmongod": error=2, No such file or directory
Caused by: java.io.IOException: error=2, No such file or directory

To use the mebedded mongodb, I have annotated my class this @DataMongoTest.

I already can say, that this file in the tmp directory is existing and it seams to be not empty. On other systems works the embedded db fine, such as on a macOS system or a debian linux server without docker. This error I’ve got seams to me as a problem using the embedded mongodb inside a docker container. I’ll run my unit tests using maven.

Do anyone have some suggestions where the error is? Thanks for help

I can finally report that my unit tests running fine 😀

For documentation reasons, here are my steps I have done to achieve that.

1. First I defined some env variables in the docker compose file:

    environment:
      - "LANG=en_US.UTF-8"
      - "LANGUAGE=en_US.UTF-8"

1. Second in the alpine docker container I run these following commands:

apk --no-cache add ca-certificates
wget -q -O /etc/apk/keys/sgerrand.rsa.pub https://alpine-pkgs.sgerrand.com/sgerrand.rsa.pub

wget https://github.com/sgerrand/alpine-pkg-glibc/releases/download/2.29-r0/glibc-2.29-r0.apk
wget https://github.com/sgerrand/alpine-pkg-glibc/releases/download/2.29-r0/glibc-bin-2.29-r0.apk

apk add glibc-2.29-r0.apk glibc-bin-2.29-r0.apk

wget https://github.com/sgerrand/alpine-pkg-glibc/releases/download/2.29-r0/glibc-i18n-2.29-r0.apk
apk add glibc-bin-2.29-r0.apk glibc-i18n-2.29-r0.apk
/usr/glibc-compat/bin/localedef -i en_US -f UTF-8 en_US.UTF-8

1. Update the versions in my project, setting these to the following:

de.flapdoodle.embed.mongo=2.2.0 (maven)
spring.mongodb.embedded.version=3.2.22 (application.properties)

Thank you for the great help over easter.
