[CONTENT SPRINT] Crossplane to Pulumi: A Migration Map for Platform Teams

[sicarul]

Why this content is interesting

• It gives platform teams a clear migration map from Crossplane concepts to Pulumi instead of treating migration as a rewrite.
• It is scheduled for 2026-05-19 as part of the content sprint's two-post-per-week cadence.

What we took into account

• We kept Kubernetes-native workflows, coexistence, import paths, and Crossplane/Pulumi terminology in view so the post meets readers where they are.
• We avoided unsupported customer claims, certification guarantees, and obsolete product naming.
• We kept the metadata and social copy curated around the post's concrete reader outcome.

Why it is useful to an end user

• End users get a practical way to evaluate whether Pulumi helps when Crossplane compositions become hard to debug or extend.
• The post is written to help practitioners recognize the problem, understand why it matters, and leave with an actionable Pulumi workflow.

Design need

• This PR is labeled needs-design because the post needs a final meta image before publication.
• Existing feature.png and meta.png files are placeholders unless Design chooses to reuse or adapt them.

Metadata

• Title: Crossplane to Pulumi: A Migration Map for Platform Teams
• Meta description: Plan a Crossplane-to-Pulumi migration by mapping compositions, claims, providers, coexistence strategies, imports, and Kubernetes-native workflows.

Docs review for PR #18963

Solid, well-scoped piece. A few issues to address before publishing — most are small style/correctness fixes, and a couple are content-accuracy notes.

Must-fix

1. Broken indentation in the TypeScript example (index.md line 87)

The closing }, { parent: this }); is severely over-indented (20 spaces) and breaks visual alignment with the opening new aws.rds.Instance(name, { line.

        new aws.rds.Instance(name, {
            allocatedStorage: args.storageGB,
            engine: "postgres",
            instanceClass: "db.t3.micro",
        }, { parent: this });

2. Ordered list style (index.md lines 32-36, 96-98, 104-108)

Per AGENTS.md: "Every item begins with `1.` to minimize diff noise." All three numbered lists use sequential numbering. Change each item to start with `1.`.

3. Heading should be sentence case (index.md line 49)

`## Side-by-side: Provisioning a database` — "Provisioning" isn't an independent clause, so it should be lowercase.

## Side-by-side: provisioning a database

Should-fix

4. First mention of Crossplane is not hyperlinked (index.md line 22)

Per the blog review criteria, "First mention of every tool, technology, or product must be hyperlinked." Link to https://www.crossplane.io/ on the first mention.

5. Outdated framing of Crossplane Compositions (index.md line 34)

Crossplane Compositions use a custom YAML-based DSL for logic.

This overlooks Composition Functions, which have been stable since Crossplane v1.17 and allow imperative logic to be written in Go, Python, KCL, etc. The current sentence will read as inaccurate to readers familiar with current Crossplane. Consider acknowledging Composition Functions while noting they add a separate runtime/operational burden compared to Pulumi's language-native model.

6. Table mapping is imprecise (index.md line 47)

ProviderConfig | Provider resource options

A Crossplane `ProviderConfig` is more directly equivalent to a Pulumi Provider resource (e.g., `new aws.Provider("name", {...})`) than to "provider resource options" (which would be the `{ provider: p }` opts bag). Suggest splitting or relabeling.

7. Weak/generic conclusion + missing CTA (index.md line 110)

The closing line ("Pulumi provides the tools you need to scale effectively") is vague and there's no `{{< blog/cta-button >}}` or specific next-step link. Migration posts should land readers on a concrete starting point — e.g., the pulumi import guide, component resources docs, or a Get Started link.

8. super() call passes args as props (index.md line 81)

`super("pkg:index:PostgreSQLInstance", name, args, opts)` — passing user args as the third argument registers them as component inputs in state. The conventional pattern is `super("...", name, {}, opts)` unless you specifically want to surface inputs. Worth changing for the example to be canonical.

Nits

9. allow_long_title: true is unnecessary (index.md line 3)

Title is 56 characters (under the 60-char limit). The flag can be removed.

10. Hedging language

"often" appears four times in close succession (lines 22, 28, 32, 36). Tighten where possible — e.g., line 22's "often lead teams" can become "lead teams".

11. Unrelated yarn.lock change

`theme/stencil/yarn.lock` drops a `@types/uuid@^8.0.0` entry. Unrelated to this blog post — please confirm this isn't merge/rebase noise that should be reverted.

Design / publishing readiness

• `social:` block present with all three keys
• `meta_image` set — PR is labeled needs-design; current image is a placeholder per the PR description
• <!--more--> break present after intro (line 26)
• Author profile exists with avatar (data/team/team/pablo-seibelt.toml, static/images/team/pablo-seibelt.jpg)
• Internal links resolve (/docs/iac/guides/migration/import/, /docs/insights/policy/)
• Title ≤60 chars
• Meta description = 147 chars (under 160)

Mention @claude if you'd like another pass after edits, or want me to draft the rewritten code block or table.

Suggestions (advisory)

These are stylistic notes — they don't block the post.

X

• Curiosity gap closed — the post lists all four concept mappings (compositions→components, claims→stack outputs, providers→packages, coexistence→import); withhold at least one so the article still has something to reveal
• "Learn more in the post" is a generic pointer — replace with a line that creates tension or signals what the reader will get

LinkedIn

• Second paragraph names every topic the guide covers (compositions, claims, providers, coexistence, imports, Kubernetes-native workflows) — the article has nothing left to reveal; cut to one or two topics and let the rest be a surprise
• Missing pointer — post ends without signaling there's more to read; add a line that connects to the article

Bluesky

• Curiosity gap closed — lists all the key concepts upfront; drop one or two to leave something for the article to deliver
• "Learn more in the post" is a generic pointer — replace with a line that creates tension

Re-review for PR #18963

Thanks for the rebase — diff is now cleanly scoped to the three blog files (no yarn.lock), and the social frontmatter now has 2 paragraphs per platform. ✅

Several items from the prior review were addressed, but a few are still outstanding and a couple of new issues surfaced in the rewrite.

Fixed since last review

• Diff scoped to the blog post only (no unrelated yarn.lock change)
• First mention of Crossplane is hyperlinked (line 30)
• allow_long_title: true removed
• Social copy now has multi-paragraph formatting for X / LinkedIn / Bluesky
• Composition Functions are now acknowledged (line 42)

Still outstanding from prior review

1. Code block indentation is still broken (index.md lines 91–95)

        new aws.rds.Instance(name, {
            allocatedStorage: args.storageGB,
            engine: "postgres",
            instanceClass: "db.t3.micro",
                            }, { parent: this });

The closing }, { parent: this }); on line 95 is indented with 28 spaces. Should be 8 to match the opening new aws.rds.Instance(name, {. Fix this →

2. Ordered lists still use sequential numbering (index.md lines 42–44, 104–106, 112–116)

Per AGENTS.md: "Every item begins with 1. to minimize diff noise." All three lists still use 1., 2., 3. (and the cutover checklist goes up to 5.). Each item should start with 1..

3. Heading should be sentence case (index.md line 57)

## Side-by-side: Provisioning a database — "Provisioning" should be lowercase. Change to ## Side-by-side: provisioning a database.

4. Table mapping is still imprecise (index.md line 55)

ProviderConfig → Provider resource options. A Crossplane ProviderConfig is more directly equivalent to a Pulumi Provider resource (new aws.Provider("name", {...})) than to the { provider: p } opts bag. Consider:

| ProviderConfig | Explicit `Provider` resource (e.g. `new aws.Provider(...)`) | Configuration for how the provider authenticates and interacts with the cloud. |

5. super() call still passes args as the third argument (index.md line 89)

super("pkg:index:PostgreSQLInstance", name, args, opts);

Passing user args here registers them as component inputs in state. Canonical pattern is super("...", name, {}, opts) unless you specifically want to surface inputs.

6. Conclusion has a link but no {{< blog/cta-button >}} (index.md line 118)

The closing inline link to Pulumi import is a step up, but blog conventions call for a {{< blog/cta-button >}} to land readers on a concrete starting point.

7. "often" still appears three times (index.md lines 30, 36, 44)

Some tightening is still possible — e.g., line 30's "often lead teams" → "lead teams", line 36's "often starts when teams" → "starts when teams".

New issues introduced in the rewrite

8. Broken sentence in the conclusion (index.md line 118)

Whether you're managing a few databases or a global multi-cloud estate, Next, pick one low-risk Crossplane composition...

The "Whether..." clause never resolves — it's spliced with a comma into a new imperative sentence ("Next, pick one..."). Reads like an edit collision. Suggest splitting:

Migrating from Crossplane to Pulumi lets your team keep the benefits of infrastructure as code while gaining the flexibility of modern programming languages. Next, pick one low-risk Crossplane composition, map its claim inputs to a Pulumi component, and use [Pulumi import](/docs/iac/guides/migration/import/) to adopt existing resources without a rewrite.

9. Two different URLs for the same pulumi import page

• Line 106: /docs/iac/guides/migration/import/ (canonical)
• Line 118: /docs/iac/adopting-pulumi/import/ (works via alias, but is the old path)

Both resolve, but it's inconsistent within a single post. Use the canonical path in both places.

10. Awkward "functions and composition functions" phrasing (index.md line 42)

Crossplane Compositions use Patch and Transform functions and composition functions to model reusable infrastructure APIs.

The repeated "functions" is rough, and "Patch and Transform" should probably be lowercase in prose ("patch-and-transform"). Consider:

Crossplane Compositions historically used patch-and-transform expressions in YAML, with Composition Functions (stable since v1.17) now allowing imperative logic in Go, Python, or KCL — though each Function runs as its own gRPC service, adding operational surface. Pulumi expresses the same logic directly in TypeScript, Python, Go, and other languages, with no extra runtime.

This more directly responds to the prior feedback about Composition Functions.

Re-review for PR #18963

Thanks for the rebase — the diff is cleanly scoped to the three blog files and the branch history is a single clean commit. ✅

However, I want to flag that the still-outstanding content issues from my previous re-review have not actually been addressed in the file — the rebase preserved the prior file state, so nothing in index.md changed since my last review. All of the items I marked "still outstanding" and "new issues introduced in the rewrite" remain.

Want me to push the fixes directly to this branch? Just say the word and I'll handle items 1–10 in a single commit.

Re-review for PR #18963

Confirmed: head is 0bbc8f0, branch is a single clean commit, PR is draft, needs-design label is removed. ✅

Images — newly regenerated, looks good

• feature.png: 1884×1256 ✅ (was 942×628 in prior reviews — now matches blog-meta-image skill default at 2× retina)
• meta.png: 1200×628 ✅ (standard OG dimensions; title text + Crossplane/Pulumi icon pair + Pulumi wordmark, on-brand purple)

The placeholder concern from prior reviews is resolved by these regenerated assets. They read cleanly as final, on-brand artwork rather than placeholders, so the meta_image publishing checkbox can be considered satisfied unless Design wants to swap them.

Content — index.md is still byte-identical to prior pass

None of the content fixes from the previous four review passes have been applied to the file. Re-stating each item against the current head (0bbc8f0):

1. Code block indentation is broken (index.md:95)

        new aws.rds.Instance(name, {
            allocatedStorage: args.storageGB,
            engine: "postgres",
            instanceClass: "db.t3.micro",
                            }, { parent: this });

Closing }, { parent: this }); is indented with 28 spaces; should be 8 to align with new aws.rds.Instance(name, {. Fix this →

2. Ordered lists still use sequential numbering (index.md:42-44, :104-106, :112-116)

Per AGENTS.md: "Every item begins with 1. to minimize diff noise." All three lists still use 1./2./3./... (cutover checklist goes to 5.). Each item should start with 1..

3. Heading should be sentence case (index.md:57)

## Side-by-side: Provisioning a database — "Provisioning" should be lowercase.

## Side-by-side: provisioning a database

4. Table mapping is still imprecise (index.md:55)

ProviderConfig → Provider resource options. A Crossplane ProviderConfig maps to an explicit Pulumi Provider resource (e.g., new aws.Provider("name", {...})), not the { provider: p } opts bag.

| ProviderConfig | Explicit `Provider` resource (e.g. `new aws.Provider(...)`) | Configuration for how the provider authenticates and interacts with the cloud. |

5. super() call still passes args as the third argument (index.md:89)

super("pkg:index:PostgreSQLInstance", name, args, opts);

Passing user args here registers them as component inputs in state. Canonical pattern is super("...", name, {}, opts) unless you specifically want to surface inputs.

6. Conclusion still has no {{< blog/cta-button >}} (index.md:118)

Migration posts should land readers on a concrete starting point via a CTA shortcode, not only an inline link.

7. "often" still appears three times (index.md:30, :36, :44)

Tighten — e.g., line 30 "often lead teams" → "lead teams"; line 36 "often starts when teams" → "starts when teams".

8. Broken sentence in the conclusion (index.md:118)

Whether you're managing a few databases or a global multi-cloud estate, Next, pick one low-risk Crossplane composition...

The "Whether..." clause never resolves — it's spliced into a new imperative sentence with a comma. Reads like an edit collision.

Migrating from Crossplane to Pulumi lets your team keep the benefits of infrastructure as code while gaining the flexibility of modern programming languages. Next, pick one low-risk Crossplane composition, map its claim inputs to a Pulumi component, and use [Pulumi import](/docs/iac/guides/migration/import/) to adopt existing resources without a rewrite.

9. Two different URLs for the same pulumi import page

• index.md:106: /docs/iac/guides/migration/import/ (canonical)
• index.md:118: /docs/iac/adopting-pulumi/import/ (old path; resolves via alias)

Use the canonical path in both places.

10. Awkward phrasing — "functions and composition functions" (index.md:42)

Crossplane Compositions use Patch and Transform functions and composition functions to model reusable infrastructure APIs.

The repeated "functions" is rough. Suggested rewrite:

Crossplane Compositions historically used patch-and-transform expressions in YAML, with Composition Functions (stable since v1.17) now allowing imperative logic in Go, Python, or KCL — though each Function runs as its own gRPC service, adding operational surface. Pulumi expresses the same logic directly in TypeScript, Python, Go, and other languages, with no extra runtime.

Design / publishing readiness

• Diff is clean (3 files only — blog post + 2 images)
• Social block — all three platforms multi-paragraph; social-review is passing
• Draft state — PR is draft, no longer blocked on design label
• meta_image set — regenerated feature.png (1884×1256) and meta.png (1200×628) are on-brand and read as final artwork
• `` break present (index.md:34)
• Author profile exists (data/team/team/pablo-seibelt.toml)
• Internal links resolve
• Title ≤60 chars
• Meta description = 147 chars

Images are now in great shape — that part of the review is unblocked. The content fixes from the prior four passes still need to be applied to index.md before this is ready to move out of draft. Items 1, 3, 8, 9 remain the highest-priority blockers (broken indentation, broken capitalization, broken sentence, inconsistent URL).
