The Go module system has greatly improved the way dependencies are managed. If you are new to Go Modules.
Public Repositories
After configuring everything correctly, it is relatively straightforward to include Go packages from public repositories. Typical starting points for me are as follows:
module github.com/Ja7ad/project
go 1.16
require (
github.com/pkg/errors
github.com/spf13/cobra
github.com/spf13/viper
)
Private Repositories
Go uses Git to pull the versions of the dependencies you specify. To access any private repositories, the git configuration for wherever Go is running (e.g. a Docker container or your laptop) needs to be configured with the appropriate credentials.
GitHub
git config --global url."https://${user}:${personal_access_token}@github.com".insteadOf "https://github.com"
GitLab
git config --global url."https://oauth2:${personal_access_token}@privategitlab.com".insteadOf "https://privategitlab.com"
# or
git config --global url."https://${user}:${personal_access_token}@privategitlab.com".insteadOf "https://privategitlab.com"
BitBucket
git config --global url."https://${bitbucket_id}:${bitbucket_token}@privatebitbucket.com".insteadOf "https://privatebitbucket.com"
CI/CD Pipeline
Dockerfile can be added via this method and add private repository to the image:
# ---------------------------------------------------------------------
# The first stage container, for building the application
# ---------------------------------------------------------------------
FROM golang:1.16-stretch as builder
COPY . /app
# Add the keys
ARG github_user
ENV github_user=$github_user
ARG github_personal_token
ENV github_personal_token=$github_personal_token
WORKDIR /app/cmd/webapp
RUN git config \
--global \
url."https://${github_user}:${github_personal_token}@@github.com".insteadOf \
"https://github.com"
RUN GIT_TERMINAL_PROMPT=1 \
GOARCH=amd64 \
GOOS=linux \
CGO_ENABLED=0 \
go build -v --installsuffix cgo --ldflags="-s" -o myapp
# ---------------------------------------------------------------------
# The second stage container, for running the application
# ---------------------------------------------------------------------
FROM alpine:3.8
COPY --from=builder /app/cmd/webapp/myapp /app/myapp
WORKDIR /app
ENTRYPOINT ["/myapp"]
You can use the following method for docker-compose.yml:
version: '3.6'
services:
app:
container_name: my_go_app_container
build:
# context can/may/will be different per-project setup
context: ../
dockerfile: GitDockerfile
args:
- github_user=private_user
- github_personal_token=private_token
image: my_go_app_image
# other configs...
SSH
Another way to do this would be to use your SSH key every time you connect, and to set .gitconfig like the following to ensure SSH is used each time:
git config --global url."git@github.com".insteadOf "https://github.com"
