我有一個(gè)使用 revel 容器化在 docker 映像中構(gòu)建的簡(jiǎn)單站點(diǎn)。我正在嘗試在 Cloud Run 中運(yùn)行此映像。不幸的是，當(dāng)我轉(zhuǎn)到該站點(diǎn)的 URL 時(shí)，我在瀏覽器中看到 502 和這條日志行2020/10/30 17:27:07 http: proxy error: dial tcp 0.0.0.0:16166: connect: connection refused我認(rèn)為它與端口有關(guān)，但我嘗試將端口最初映射到 9898，但我仍然在日志行中看到一個(gè)隨機(jī)端口號(hào)。${PORT}目前，我已按照 GCP 文檔的建議將我的 revel 應(yīng)用程序中的端口設(shè)置為。我應(yīng)該提到我可以毫無(wú)問(wèn)題地在本地部署容器。Dockerfile：FROM golang:1.15 AS buildENV CGO_ENABLED 0ADD . /go/src/app# Install revel frameworkRUN go get -u github.com/revel/revelRUN go get -u github.com/revel/cmd/revel# Run revel appEXPOSE ${PORT}ENTRYPOINT revel run -a /go/src/app -p ${PORT} -m dev狂歡 app.conf 片段：# The IP address on which to listen.http.addr = 0.0.0.0# The port on which to listen.http.port = ${PORT}更新：建議使用硬編碼的 8080 端口，看看是否可行。我仍然看到 502。我嘗試再次在本地運(yùn)行它，看起來(lái) revel 試圖在一個(gè)端口上設(shè)置，然后在另一個(gè)端口上作為反向代理進(jìn)行偵聽(tīng)。因此，除非我認(rèn)為這可能是一個(gè)狂歡問(wèn)題，而不是 Cloud Run 問(wèn)題docker run --publish 8080:8080 appRevel executing: run a Revel applicationChanged detected, recompilingParsing packages, (may require download if not cached)...
