Erro na hora de gerar a imagem do Docker

Peguei a parte FROM jdk:17-oracle em um fórum, já que o professor está usando o java mais antigo.

Erro:

PS C:\workspace\ws-alura\forum\forum> docker build -t alura/forum .
error during connect: This error may indicate that the docker daemon is not running.: Post "http://%2F%2F.

Meu Dockerfile:

FROM jdk:17-oracle
RUN addgroup -S spring && adduser -S spring -G spring
USER spring:spring
ARG JAR_FILE=target/*.jar
COPY ${JAR_FILE} app.jar
ENTRYPOINT ["java", "-jar", "/app.jar"]
