构建映像失败，尝试创建 docker 映像时未发现摘要错误

Question

在 eclipse 终端中，我正在尝试创建 Springboot 项目的 docker 映像。

命令： mvn spring-boot:build-image

最后我得到No digest found error

[ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.4.5:build-image (default-cli) on project PROJECT_NAME: Execut

有人可以帮我吗。

Answer 1

@ANEESH TG，我尝试了以下工作正常的方式。

a) 为 SpringBoot 项目创建一个名为Dockerfile的 Docker 文件，详细信息如下

FROM openjdk:8-jdk-alpine
ARG JAR_FILE=target/*.jar
COPY ${JAR_FILE} app.jar
ENTRYPOINT ["java","-jar","/app.jar"]

b) 打开该项目的 Eclipse 终端，Select 项目->右键单击->在本地终端中显示->终端

c) 运行低于命令

docker build -t springio/gs-spring-boot-docker .

在这里你 go....!!
