I am building a Linux docker-image using a docker file in which there is a command to install python3-dev and pip3. The python3-dev is getting installed perfectly but pip3 is getting errors. What is the proper syntax for installing pip3

RUN apk add pip3 install --upgrade pip

Error is:

Step 3/3 : RUN apk add pip3 install --upgrade pip ---> Running in 71181984d781 fetch http://dl-cdn.alpinelinux.org/alpine/v3.10/main/x86_64/APKINDEX.tar.gz fetch http://dl-cdn.alpinelinux.org/alpine/v3.10/community/x86_64/APKINDEX.tar.gz ERROR: unsatisfiable constraints: install (missing): required by: world[install] pip (missing): required by: world[pip] pip3 (missing): required by: world[pip3] The command '/bin/sh -c apk add pip3 install --upgrade pip' returned a non-zero code: 3

pip3 install is its own command. You don't need apk add

However, extending the existing python alpine image might make it easier

And the recommended way would actually be

RUN python3 -m pip install --upgrade pip
