libzmq.so.5 library not found

[wangqingpen]

docker compilation has been completed but docker keeps restarting, the log is as follows
Shows missing .so file, but I've installed it in dockerfile, dockerflie file as follows

It definitely looks like a link library loading issue. Are you using c linkage when compiling the go binary?

Is this your own code, or something on github.com/edgexfoundry? What tag/branch/component is failing?

[wangqingpen]

Yes, I rewrite modbus But I've put the link library in ，Pls is there any way to fix it thanks

[bnevis-i]

Can you share the full contents of the Dockerfile and Makefile that you are using?

Lastly, what version of the go device SDK are you using?

[wangqingpen]

v2

[jiekechoo]

Please try run docker container manully: docker run -it --rm --entrypoint sh edgexfoundry/docker-device-dlt698.45-go:1.3.1, and use command: find / -name libzmq.* check libzmq has installed.

[wangqingpen]

already installed

[jiekechoo]

Can you make build in your develop host, and run it manully? Paste all build progress and run log here.

[wangqingpen]

make build

logs

[wangqingpen]

This is normal operation

One thing that seems suspicious to me is the number of FROM lines in the Dockerfile:

ARG BASE=golang:1.17-alpine3.12
FROM ${BASE} AS builder
...
FROM golang:1.17-alpine AS builder
...
FROM alpine:3.12

It is critical that the build container uses the same base version of alpine as the runtime container. Here, the middle FROM statement doesn't specifically lock down the alpine version.

It looks like it is looking for libzmq.so.5 in both cases, and it is unlikely there would be a breaking change without rolling the major version. But, I thought I would mention the anomaly.

[wangqingpen]

ARG BASE=golang:1.17-alpine3.15
FROM ${BASE} AS builder

FROM alpine:3.12 I've changed it to the above command, and it still gets the same error

@wangqingpen , please upgrade to EdgeX 3.1 (just released). We have removed ZMQ as a dependency as of EdgeX 3.0.
https://wiki.edgexfoundry.org/display/FA/Napa

[wangqingpen]

Because my other services are all v2 versions

[cloudxxx8]

You can remove the zero mq from the Docker file and rebuild all the go binary with no_zmq build tag

[cloudxxx8]

https://github.com/edgexfoundry/edgex-go/blob/4f1b2626cb078c7149dc655301029b2517b4b500/Makefile#L83

[wangqingpen]

You mean to remove zmq and put NO_ZMQ_GO_BUILD_TAG:=no_zmq into the dockerfile?

[cloudxxx8]

remove zmq from Docker file
put no_zmq to your go build command
