panic: runtime error: invalid memory address or nil pointer dereference

 

 

 

CA certificate is a problem, the solution is to copy the certificate alpine in the mirror

 

Attach dockerfile Code

# Base image is busybox docker warehouse of 
the FROM Alpine AS certs 
RUN APK APK Update && the Add CA-Certificates 
# mirror copy certificates from other 
the FROM busybox 
COPY the --from = certs / etc / ssl / certs / etc / ssl / certs 
# On the signature 
LABEL author = "[email protected]" 
# working directory 
WORKDIR / root 

# Add files 
the ADD ./bin/ddkt-poster-go ./ddkt-poster-go 
the ADD ./bin/conf.toml ./conf. toml 
the ADD ./fonts ./fonts 
# expose the port number 
#EXPOSE 8080 
password when performing the operation of container # 
EntryPoint [ "./ddkt-poster-go", "-conf", "conf.toml"]
