Not work in docker container

[vhar]

Sorry, I can't reopen the #315 issue.

Unfortunately, nothing helped.

1. If run the application

go run ./main.go -tags go_tarantool_ssl_disable 

• the same errors.

2. If install opensll to golang:1.20-alpine container - the same errors
   Dockerfile

FROM golang:1.20-alpine
WORKDIR "/usr/src/tarantool"

RUN apk add --update openssl && \
    rm -rf /var/cache/apk/*

4. If build a custom container from ubuntu:latest - the same errors
   Dockerfile

FROM ubuntu:latest
WORKDIR "/usr/src"

RUN apt-get update \
    && apt-get -y install \
    wget \
    tar \
    openssl \
    ca-certificates \
    libssl-dev \
    && apt-get clean; rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/* /usr/share/doc/*

RUN update-ca-certificates -v

RUN wget https://go.dev/dl/go1.20.6.linux-amd64.tar.gz \
    && tar -C /opt -xzf go1.20.6.linux-amd64.tar.gz

ENV PATH="$PATH:/opt/go/bin"

I'll check the docker images in a few days.

I'm sorry, you need to run the application with the command if you don't need OpenSSL/TLS support:

go run -tags go_tarantool_ssl_disable ./main.go

instead of:

go run ./main.go -tags go_tarantool_ssl_disable

For the future generations: I've had similar issue using

go build -tags go_tarantool_ssl_disable -tags go_tarantool_call_17

instead of

go build -tags go_tarantool_ssl_disable,go_tarantool_call_17

It really hard to distinct invalid tag setup from tags not working in Go.

@DifferentialOrange
If I want to user ssl in docker container, how I should fix it?

You need to install OpenSSL + dev files for compilation into the image before build.

I think you don't install header files for the OpenSSL or a C compiler or something wrong with the environment. We have an example how to build OpenSSL, but on CI, not inside a docker image:

https://github.com/tarantool/tt/blob/5fea6e16448598c67afa534e93010f4b1d2f70ae/.github/workflows/publish.yml#L31-L37

But it could help.

I showed above an example of how I build custom docker container. Everything that is needed is installed in it (openssl, libssl-dev) , but at startup it still has the same errors.
If install samething on a virtual machine with the same options, then there are no errors. This is clearly a problem when working with a docker container.
I took the advice and start program with the go_tarantool_ssl_disable tag. Everything works without problems.
