Only upload of valid PEM files will be accepted

build & run

go run

cd file-upload # move directory to this project
# run application
go run cmd/app/main.go

run from compiled binary

get a release on the release page

# extract binary
tar xzf file-upload_<version>_<arch>.tar.gz

# run binary
./file-upload

build docker image

cd file-upload # move directory to this project
docker build -t file-upload:latest -f build/package/Dockerfile .

run docker image

docker run -p 4500:4500 file-upload:latest

upload certificates

a single certificate with curl

cd file-upload # move directory to this project
curl -X POST -u user:secret -F file=@test/github.crt.pem http://localhost:4500/upload

multiple certificates with curl

just repeat the -F file=@/path/to/file.pem part in your command

from web UI

just connect to http://localhost:4500, login and choose the file(s) to upload, press on submit.

todo

• run behind https
• do not crash container on cert validation (ie: cert expired time="2020-12-23T17:01:26Z" level=fatal msg="failed to verify certificatex509: certificate has expired or is not yet valid: current time 2020-12-23T17:01:26Z is after 2020-12-11T13:04:36Z" )
• do not crash container when file is invalid (ie: 2020/12/23 16:52:46 http: superfluous response.WriteHeader call from github.com/dadez/file-upload/pkg/upload.UploadHandler (upload.go:57))
• prettier web part
