I found a related issue on github but it is under the msphpsql repo so I'm not sure if it applies to the driver in general for alpine. It says MS does not support yet.
Official MS installation page has installation instructions only for Debian, RedHat, SUSE, Ubuntu.
If there are any workarounds, please suggest.
If this is not possible, please elaborate your answer as technically as possible. I could not find a suitable answer for this question anywhere.
This is the Dockerfile I've tested.
FROM alpine
# Install dependencies
RUN apk --no-cache add curl gnupg
# Download the desired package(s)
RUN curl -O https://download.microsoft.com/download/e/4/e/e4e67866-dffd-428c-aac7-8d28ddafb39b/msodbcsql17_17.6.1.1-1_amd64.apk
RUN curl -O https://download.microsoft.com/download/e/4/e/e4e67866-dffd-428c-aac7-8d28ddafb39b/mssql-tools_17.6.1.1-1_amd64.apk
# (Optional) Verify signature, if 'gpg' is missing install it using 'apk add gnupg':
RUN curl -O https://download.microsoft.com/download/e/4/e/e4e67866-dffd-428c-aac7-8d28ddafb39b/msodbcsql17_17.6.1.1-1_amd64.sig
RUN curl -O https://download.microsoft.com/download/e/4/e/e4e67866-dffd-428c-aac7-8d28ddafb39b/mssql-tools_17.6.1.1-1_amd64.sig
RUN curl https://packages.microsoft.com/keys/microsoft.asc | gpg --import -
RUN gpg --verify msodbcsql17_17.6.1.1-1_amd64.sig msodbcsql17_17.6.1.1-1_amd64.apk
RUN gpg --verify mssql-tools_17.6.1.1-1_amd64.sig mssql-tools_17.6.1.1-1_amd64.apk
# Install the package(s)
RUN apk add --allow-untrusted msodbcsql17_17.6.1.1-1_amd64.apk
RUN apk add --allow-untrusted mssql-tools_17.6.1.1-1_amd64.apk
and this is the log I got,
