How are you running postgres?

[Aminu Babayo Shehu]

Uusing hikaricp

[Kristian Nedrevold]

I mean, is postgres also running in docker? And if so it is running in the same docker network?

[Aminu Babayo Shehu]

No

[Aminu Babayo Shehu]

The postgres is on the server

[Kristian Nedrevold]

Have you tried running the container with the --network="host" flag?

[Kristian Nedrevold]

Or you could also try to substitute localhost with host.docker.internal

[Aminu Babayo Shehu]

# Use the official gradle image to create a build artifact.
FROM gradle:7-jdk11 as builder

# Copy local code to the container image.
COPY build.gradle.kts .
COPY gradle.properties .
COPY src ./src

# Build a release artifact.
RUN gradle installDist

FROM openjdk:11
EXPOSE 7000:7000
RUN mkdir /app
COPY --from=builder /home/gradle/build/install/gradle /app/
WORKDIR /app/bin
CMD ["./gradle"]

Above is my Dockerfile, where can I insert the --network="host" flag?

[Kristian Nedrevold]

That is part of the run configuration

[Aminu Babayo Shehu]

ohk so how can I do now?

[Kristian Nedrevold]

I haven't used the docker-cli in a while but I imagine it's something like:
docker run --network="host" <image>

[Aminu Babayo Shehu]

ohk let me try, thank you Sir.

[Kristian Nedrevold]

For local dev environments I recommend checking out docker-compose https://docs.docker.com/compose/

[Aminu Babayo Shehu]

Ohk Sir, thank you.

[Aminu Babayo Shehu]

Hello Sir, the first suggestion for using the network flag works. Thank you so much
