Is it possible to build image from Dockerfile and run it with a single command?
There is one command docker build to build a Dockerfile and docker run -it to run the image.
Is there any combination of these two commands to make it easier to build and run with just one command?

If you want to avoid tagging, docker build -q outputs nothing but the final image hash, which you can use as the argument to docker run:
docker run -it $(docker build -q .)And add --rm to docker run if you want the container removed automatically when it exits.
docker run --rm -it $(docker build -q .)No, there is no single command. But if you tag your image as you build it, it will be easier to run:
docker build -t foo . && docker run -it fooI use docker-compose for this convenience since most of the apps I'm building are talking to external services sooner or later, so if I'm going to use it anyway, why not use it from the start. Just have docker-compose.yml as:
version: "3"
services: app: build: .and then just run the app with:
docker-compose up --build appIt will rebuild the image or reuse the container depending on whether there were changes made to the image definition.
0Recently I started getting a promo message about using docker scan after every build.
Use 'docker scan' to run Snyk tests against images to find vulnerabilities and learn how to fix them
Here's what I used to do:
docker build -q .and here's what is working now:
docker build -q . | head -n1If you use Makefile, I find this snippet useful:
build: @docker build . | tee .buildlog
bash: build @docker run --rm -it $(shell grep "Successfully built" .buildlog | cut -d ' ' -f 3) /bin/bashYou don't need tagging, like in @jonathon-reinhart answer, but you also get the build output.
You can also do docker build and pipe image name which it outputs to docker run:
docker build . | tail -n1 | cut -d' ' -f3 | xargs -I{} docker run {}docker buildwill give you multi-line text... Successfully built 18e77bc0d83a- you get the last line with
tail -n1 - split by
' 'and get3rd word withcut -d' ' -f3 - pass it as argument to
runwithxargs -I{} docker run {}
For anyone looking for a reusable solution, you could install this docker plugin which i created:
Then you could build and run a Dockerfile as follows:
docker script ./DockerfileWindows PC
Make a run.bat file. Then in the file add this:
docker build -t foo .
docker run -it fooTo run the file using powershell or cmd do this:
./run.batdocker-build-and-run
I've created a little helper command for building and running, in a single command. On Linux or Mac, you can add this to your ~/.bash_profile to make it available in the Terminal.
Usage:
docker-build-and-run BUILD_ARGS [-- RUN_ARGS] [-- RUN_COMMAND]Examples:
docker-build-and-run . -- npm run test
docker-build-and-run --file ./Dockerfile . -- -v ~/volume:/var/volume -- node server.jsThe Script:
Add this to a .sh file, or add it to your ~/.bash_profile:
TERM_GREEN="\033[1;32m"
TERM_BLUE="\033[1;34m"
TERM_NC="\033[0m"
docker-build-and-run() { if [[ -z "$@" ]]; then echo " Usage: docker-build-and-run BUILD_ARGS [-- RUN_ARGS] [-- RUN_COMMAND] Examples: docker-build-and-run . -- npm run test docker-build-and-run --file ./Dockerfile . -- -v ~/volume:/var/volume -- node server.js " return fi # Extract the segments between the dashes: BEFORE_THE_DASHES= while (( "$#" )); do if [[ "$1" = "--" ]]; then shift break fi BEFORE_THE_DASHES="$BEFORE_THE_DASHES $1" shift done SEGMENT_1=$BEFORE_THE_DASHES BEFORE_THE_DASHES= while (( "$#" )); do if [[ "$1" = "--" ]]; then shift break fi BEFORE_THE_DASHES="$BEFORE_THE_DASHES $1" shift done SEGMENT_2=$BEFORE_THE_DASHES SEGMENT_3=$@ BUILD_ARGS=$SEGMENT_1 RUN_ARGS=$SEGMENT_2 RUN_COMMAND=$SEGMENT_3 if [ -z "$RUN_COMMAND" ]; then RUN_COMMAND=$RUN_ARGS RUN_ARGS= fi TEMP_TAG=docker-build-and-run-temp docker rm -f $TEMP_TAG 2>/dev/null printf "${TERM_GREEN}Building Docker container (${TERM_BLUE}docker build $BUILD_ARGS${TERM_GREEN})${TERM_NC}\n" \ && docker build --tag $TEMP_TAG $BUILD_ARGS \ && printf "${TERM_GREEN}Running Docker container (${TERM_BLUE}docker run $RUN_ARGS $RUN_COMMAND${TERM_GREEN})${TERM_NC}\n" \ && docker run --rm -it $RUN_ARGS --label $TEMP_TAG $TEMP_TAG $RUN_COMMAND
