Hi,
Managed to get it working. For anyone else that has this issue, make your dockerfile look like this so as to add the certificate to chromium cert storage:
FROM golang:1.19-bullseye as builder
RUN go install -trimpath go.k6.io/xk6/cmd/xk6@latest
RUN xk6 build --output "/tmp/k6" --with github.com/grafana/xk6-browser@main
FROM debian:bullseye
RUN apt-get update && \
apt-get install -y chromium &&\
apt install -y libnss3-tools curl &&\
apt-get install -y ca-certificates
COPY ./certs/myroot.crt /usr/local/share/ca-certificates/myroot.crt
COPY ./certs/myroot.crt /usr/local/share/ca-certificates/myroot.pem
RUN chmod 644 /usr/local/share/ca-certificates/myroot.crt && \
update-ca-certificates
RUN mkdir -p $HOME/.pki/nssdb
RUN certutil -d $HOME/.pki/nssdb -N --empty-password
RUN certutil -d sql:$HOME/.pki/nssdb -A -t "C,," -n myroot -i /usr/local/share/ca-certificates/myroot.pem
COPY --from=builder /tmp/k6 /usr/bin/k6
ENV XK6_HEADLESS=true
ENTRYPOINT ["k6"]
Many thanks for the amazing tool your guys are working on here!
