[Docker] docker build 現在不會印出中間層映像檔的 ID 了?
今天想要從 Dockerfile 建立出 Docker 映像檔時,
因為 Ubuntu 22.04 的 APT 找不到 Azure CLI 2.29.2-1,所以失敗了:
$ docker build -t deploy-cd . [+] Building 5.9s (22/26) ...... => [ 1/23] FROM docker.io/library/ubuntu:22.04@sha256:2a7dffab37165e8b4f206f61cfd984f8bb279843b070217f6ad310c9c31c9c7c 0.0s => CACHED [ 2/23] RUN apt-get update 0.0s => CACHED [ 3/23] RUN apt-get install -y gnupg 0.0s => CACHED [ 4/23] RUN apt-get install -y curl 0.0s ...... => CACHED [18/23] RUN apt-get install -y terraform=0.13.3 0.0s => ERROR [19/23] RUN apt-get install -y azure-cli=2.29.2-1~$(lsb_release -cs) 4.4s ------ > [19/23] RUN apt-get install -y azure-cli=2.29.2-1~$(lsb_release -cs): #22 1.417 Reading package lists... #22 3.618 Building dependency tree... #22 4.221 Reading state information... #22 4.246 Package azure-cli is not available, but is referred to by another package. #22 4.246 This may mean that the package is missing, has been obsoleted, or #22 4.246 is only available from another source #22 4.246 #22 4.271 E: Version '2.29.2-1~jammy' for 'azure-cli' was not found ------ executor failed running [/bin/sh -c apt-get install -y azure-cli=2.29.2-1~$(lsb_release -cs)]: exit code: 100
記得以前都會在執行 docker build
時,
把每一個中間層的 ID 印出來,這樣就可以進到最後一層去看看為什麼會失敗。
但現在 docker build
的輸出,完全沒有中間層的 ID 耶?
查了一下,原來現在得要加上 DOCKER_BUILDKIT=0
這個環境變數,
才會顯示出中間層的 ID,
同時也會把每個指令的輸出都印出來,就和以前一樣:
$ DOCKER_BUILDKIT=0 docker build -t deploy-cd .

如上,在第 19 步時失敗了,
因此我們就可以進到第 18 步建出來的中間層 c21780201c38 去試看看:
docker run -it c21780201c38 /bin/bash
進到這一層之後,就可以嘗試看看,
怎樣才能將想要的 Azure CLI 版本裝上去囉~
