高山码头集装箱内的 dlv seg 故障

Question

我在 alpine:3.7.1 容器中运行 dlv。它因此错误而崩溃：

/ # /dlv --listen=:40000 --headless=true --api-version=2 exec /server

Could not create config directory: user: Current not implemented on linux/amd64.panic: runtime error: invalid memory address or nil pointer dereference

[signal SIGSEGV: segmentation violation code=0x1 addr=0x50 pc=0x8c7dca]

我的文件：

# Compile stage

FROM golang:1.10.1-alpine3.7 AS build-env

ENV CGO_ENABLED 0

ADD . /go/src/hello

# The -gcflags "all=-N -l" flag helps us get a better debug experience

#RUN go build -x -gcflags "all=-N -l" -o /server hello

RUN go build -gcflags "all=-N -l" -o /server hello

# Compile Delve

RUN apk add --no-cache git

RUN go get github.com/derekparker/delve/cmd/dlv

如果我改变FROM golang:1.10.1-alpine3.7 AS build-env到FROM golang:1.10-alpine3.7 AS build-env/dlv 开始正常工作并且不再崩溃。我认为此更改可确保构建容器与运行时容器相同。
