Instalation as cmd

Usage

po3rin/gocker config file

create Gockerfile.yaml (Gockerfile supports only 3 fields)

#syntax=po3rin/gocker

repo: github.com/po3rin/gockerfile
path: ./example/server
version: v0.0.1 # default master

repo is git repository. path is path to main.go.

Build Gockerfile using docker build

you can build Gockerfile.yaml with docker build

$ DOCKER_BUILDKIT=1 docker build -f Gockerfile.yaml -t po3rin/gockersample .

Build Gockerfile with builtctl

using as buildkit frontend.

buildctl build \
		--frontend=gateway.v0 \
		--opt source=po3rin/gocker \
		--local gockerfile=. \
		--output type=docker,name=gockersample | docker load

Run container

You can run go API container as it is.

$ docker run -it -p 8080:8080 po3rin/gockersample:latest /bin/server
$ curl localhost:8080/

gockerfile's Issues

Use git source

Just a comment after looking at the code.

gockerfile/gocker2llb.go

Line 38 in 3e829bf

Run(llb.Shlex("git clone https://" + c.Repo + ".git /go/src/" + c.Repo)).

could use the builtin git source llb.Git() https://godoc.org/github.com/moby/buildkit/client/llb#Git instead (probably with AddMount()). The benefit of git source is that it automatically invalidates the cache when remote repo gets updated.

change sypport name for --local option

there is a bug (fixed #5 ). I should build public image.

buildctl build \
		--frontend=gateway.v0 \
		--frontend-opt=source=$(GATEWAY_IMAGE) \
		--local gockerfile=. \
		--local context=. \
		--exporter=docker \
		--exporter-opt name=$(IMAGE) | docker load

--local dockerfile returns following error

------
 > [internal] load Gockerfile from Gockerfile.yaml:
------
error: failed to solve: rpc error: code = Unknown desc = got error getting gockerfile: failed to resolve dockerfile: rpc error: code = Unknown desc = local source dockerfile not enabled from the client

failed to resolve Gockerfile when docker build

found bug

docker build -f Gockerfile.yaml -t po3rin/gockersample .
------
 > [internal] load Gockerfile from Gockerfile.yaml:
------
rpc error: code = Unknown desc = got error getting gockerfile: failed to resolve Gockerfile: rpc error: code = Unknown desc = local source gockerfile not enabled from the client

Update buildctl to v0.0.4.

should edit Makefile

WARN[0000] --exporter <exporter> is deprecated. Please use --output type=<exporter>[,<opt>=<optval>] instead.
WARN[0000] --frontend-opt <opt>=<optval> is deprecated. Please use --opt <opt>=<optval> instead.

Add supports local path to main.go

Now, only supports remote repository file...
