Appreciate any guidance on a subdirectory deployment

[saedabdu]

Hello folks,

I'm having a hard time getting my WP deployment to properly work without any broken links trying to have it served under a subdirectory /blog.
I have used info from Codex to have those changes incorporated in the image. but no success so far.
Also in my k8s ingress i have this configuration snippet which handles the rewriting rules as follows,

nginx.ingress.kubernetes.io/configuration-snippet: |
  rewrite /blog/(.*) /$1 break;
  rewrite /wp-admin(.*) /blog/wp-admin$1 break;

I still have those 404 when trying to publish new posts.

Any guidance is extremely appreciated.

See #221 (comment) and #133 (comment). When you create your wordpress container, you'll want to specify a workdir of /var/www/html/blog so that WordPress is aware it is living in a /blog/ subdirectory.

Thanks @tianon for your prompt response, much appreciated.

Indeed i have came across those threads #221 and #133 I made sure I have a WORKDIR in my

This is what i get

No modifications made to the docker-entrypoint.sh.

Not sure why you're duplicating so much of this repo's source, can you elaborate?

I was able to get this to work with the following simplified Dockerfile (which should be pretty easy to extend to include your COPY for the theme you're installing, although that would likely be better to drop into /usr/src/wordpress so that it gets copied appropriately even when /var/www/html is a volume):

FROM wordpress:php7.1-apache
WORKDIR /var/www/html/blog

(Closing, since this is answered the best we can. 👍)

My attempt to change the WORKDIR results in the homepage being served but article pages causing error script '/var/www/html/index.php' not found or unable to stat. I think the mod-rewrite is somehow not working.

[loeffel-io]

can confirm that it's very easy:

pkg_tar(
    name = "wp_content",
    srcs = glob(["wp-content/**"]),
    package_dir = "/usr/src/wordpress",
    strip_prefix = ".",
    visibility = ["//visibility:public"],
)

container_image(
    name = "wordpress_image",
    base = "@wordpress_6_1_apache//image",
    tars = [
        ":wp_content",
    ],
    workdir = "/var/www/html/blog",
    visibility = ["//visibility:public"],
)

siteurl and home needs to be http://localhost/blog in my case

btw: crazy how many trash solutions are out there for this problem
